1.2 Information on engineering, hydrogeological conditions of the construction area

1.2.1 Climatic conditions

According to climatic conditions, B. Sochi belongs to the IV-B zone, allocated to the southern region of the Black Sea province. The main features of the climate are hot, humid summers, warm winters and autumn, long spring. The winter period is characterized by periodic instability associated with the invasion of cold air masses. In the coastal zone of B. Sochi, the duration of the frost-free period is 289310 days. The average annual air temperature is + 14.1 ° C, the absolute maximum is + 38 ° C, the annual amplitudes of the temperature variation are 1819 °. In valley lowlands, decreases to 20 ° are possible. The average relative humidity is 6870%, the amount of precipitation falling for the year is 1605 mm, in September-April 1279 mm falls, in May-August - 326 mm, the number of days with snow cover reaches 9, the snow cover capacity usually does not exceed 1030 cm. The average wind speeds of local circulation do not exceed 1.9 m/s. in summer and 2.8 m/s. - in winter. The maximum maximum wind speeds for the Tuapse-Sochi region are taken to be 25 m/s, the strongest winds are southeast. Fog on the coast occurs mainly in winter and spring, the number of days with them reaches 58. Seismicity of the construction site - 8 points.

1.2.2 Geomorphological conditions

Geomorphologically, the construction site is the remains of an ancient Black Sea terrace composed of light brownish-yellow clays, at the base of which lies the basal horizon of pebbles. The basement of the terrace is formed by the blurred surface of the argillites of the Sochi retinue of the lower Oligocene.

1.2.3 Geological structure of the site

The geological structure of the site is represented by indigenous deposits of the Paleogene and Quaternary formations of various genesis.

The indigenous base of the slope of the Sochi River Valley is composed of rocks of the Sochi retinue of the Oligocene - argillites gray, layered, with thin sandstone layers.

Quaternary deposits are represented by soils of various genesis: these are bulk man-made soils, deluvial-belt clays with landslide breccia of argillites, marine pebble deposits, elyuvium of native rocks.

According to surveys (including previous years), the following lithologenetic groups are identified in the geological structure of the site from top to bottom along the section to a depth of 32.0 m:

Class of man-made dispersed soils.

Group of disconnected natural displaced bulk formations. Layer 1 - Dispersed associated naturally displaced bulk clay non-swelling soils - brown clay, brownish - gray to gray, loose, with fragments of argillite, sandstone, with a large amount of construction debris (concrete, brick, household garbage). The thickness of bulk soils is 0.5-1.5 m, rarely increasing near underground structures and communications to 2-3 m. They are widespread almost everywhere.

Class of natural dispersed soils

B. Group of connected sedimentary polymineral clay soils. Layer 2 - Dispersed natural sedimentary deluvial-bearing soils - yellow-brown clay, gray spots, semi-solid, dense, swelling, with an admixture of sandy material, with pebbles (up to 1015%), with fragments of weathered argillite and sandstone (up to 1525% by layer). The thickness of the soils of layer 2 is on the surface of the Ancient Sea terrace 1112 m, decreasing higher along the slope (within the indigenous ledge) to 2-5 m. The soils of the layer are developed everywhere from the surface of the earth or under the embankment.

B. Group of incoherent sedimentary coarse soil.

Layer 3 - Dispersed incoherent natural ancient Roman pebble soils of the Karagant terrace - pebbles of sedimentary and metamorphic rocks, large and medium, gravel with sandy-clay aggregate up to 2025%, with large boulders of cooked sandstone. Pebbles have a power of 2-4 m.

B. Group of connected sedimentary polymineral clay soils.

Layer 4 - Dispersed coherent natural sedimentary eluvial soils - argillite brown to grayish-brown, wormless and obscure, weathered to hard clay and debris, weak, highly fractured. The thickness of the eluvium is marked in the roof of the indigenous massif. The thickness of the soils of layer 4 varies within 0.52.0 m. Soils of layer 4 are marked in the western part of the area under consideration .

Layer 5 - Dispersed incoherent sedimentary softening, waterproof, layered eluvial soils - argillite brownish-gray to gray, layered in the massif, iron-lined by steep cracks and spraying, with layers of sandstone brown, cracked. The soil of layer 5 is marked by local distribution in the western part of the area under consideration, in the roof of the bedrock, its thickness varies from 0.5-1.0 to 1-5 m. The soil is a transitional type of argillite from weathered differences to the bedrock.

Class of natural rock soils

G. Group of semi-rock soils.

Layer 6 - Semi-rock sedimentary low - low strength softened, low water permeable, layered, fractured soils - argillite gray, layered, at separate intervals broken, leafy, with vertical microcracks, with thin (2-7 cm) sandstone layers. During boreholes penetration in the core stratum, interlayers of brecciated, sheet argillite, sandstone stratum and calcite stratum are marked. The fall of rock formations is noted in azimuths of 260330 °, falling angles of 515 °.

1.2.4Hydrogeological conditions

Hydrogeological conditions of the site are characterized by the distribution of:

a) permanent aquifer confined to terrace sediments;

b) crack waters marked in the bedrock at depths more than 1220 m from their roof;

c) groundwater of the headwaters type.

The permanent groundwater horizon is confined to the lower reaches of the ancient Roman pebble terrace, which serves as a good natural groundwater collector - it discharges groundwater from the lower part of the slope. The groundwater mirror of this horizon is marked at abs. Elevations 23.0-24.0 m. Dense differences in the bedrock serve as a watershed for this horizon. The groundwater of the permanent horizon is fed mainly due to atmospheric precipitation and due to groundwater coming from the upper sections of the slope.

The groundwater horizon of the fractured type has a limited distribution, groundwater of this type is marked in eluvium or confined to zones of increased fracture in native rocks.

The headwater appears in the autumn-winter period in clay soils almost everywhere at depths of 3-4 m about 0.8-1.2 m. The headland is fed both due to atmospheric precipitation and due to leaks of domestic waters from dilapidated water-carrying communications.

The headwaters and groundwaters of ancient Roman pebble deposits are non-aggressive to concrete on all types of cement. Water - medium of fractured waters is weakly aggressive to concrete of W4 grade by waterproofness (SNiP 2.03.1185, vol. 6).

1.2.5 Physical and geological processes and phenomena

Unfavorable physical and geological features of the site include the fact that the designed construction is planned on an old-earth slope. The survey site is located in the contour of the ancient landslide G655 with a length of 300 m, a width of 425 m, a capacity of 7.0 m. The basis for the displacement of this landslide by SKGEC geologists is designated ul. Krasnoarmeyskaya. Landslide activity in the isolated circuit has not been manifested for more than 30 years.

1.3 Solutions and Key Indicators

according to the master plan and improvement of the site

The land plot provided for the design and construction of a residential building is located in the reconstruction zone of the central part of the city of Sochi, Krasnodar Territory.

The triangular section is bounded by the existing urban, multi-storey building and borders:

from the north - with 2-5 storey residential buildings;

from the east - bounded by the street. Krasnoarmeyskaya;

from the southwest - bounded by the street. Vinogradnaya, on the opposite side of which begins the territory of the Riviera park.

The relief of the site is flat, with a significant difference in elevation from 40.0 m to 18.0 m in the north direction and a sharp difference in elevations from 25.0 m to 12.6 m in the area adjacent to ul. Krasnoarmeyskaya.

Currently, the territory is built up with buildings and structures of the former brewery to be demolished. Communications existing on the site are partially subject to transfer, partially subject to complete dismantling.

Objects existing on the territory to be developed, as well as on residential buildings on plots adjacent to the quarter under consideration, are not included in the list of historical and cultural monuments.

The master plan is developed in accordance with the layout limitation scheme. Planning decisions of the master plan are made taking into account the specifics of the existing topography of the territory, when designing the vertical layout of cutting and filling of soil, they are provided in a minimum amount in order to preserve the existing topography in order to avoid the appearance of landslide processes after the development of the construction site.

The designed complex consists of single-section buildings of high storey freely arranged along the perimeter of the triangular section - a layout predetermined by the configuration of the section. The buildings are located along Vinogradnaya Street and in the northeastern part of the territory on the street. Krasnoarmeyskaya.

The vertical layout is solved taking into account the existing terrain, stormwater removal is carried out along driveways and platforms to lowered places.

The construction area is being improved. The main entrances to the complex are decided from ul. Vinogradnaya and st. Krasnoarmeyskaya. The driveways and turning platforms are supposed to be made with a two-layer asphalt concrete surface framed with on-board concrete stone BR 100.30.18 .

Pavements, areas in front of entrances to residential buildings are provided with concrete pavement. Paving of sidewalks and platforms in front of the entrances to public buildings uses paving tiles made of colored concrete .

The territory, free from development and hard coatings, is sown by lawn grass, landscaped by planting decorative trees of valuable species and shrubs.

The project provides for measures to ensure the life of low-mobility population groups.

1.4 Substantiation of architectural and construction solution of residential building No. 1

The peculiar configuration of the site allocated for the construction of a residential complex - a rectangular triangle, predetermined the basic principle of layout: four towers located along ul. Vinogradnaya - one-section 16-story buildings .
