Introduction.

In this course project, in the discipline "Foundations and Foundations," shallow foundations and pile foundations are calculated and designed. The necessary data on engineering and geological surveys, diagrams of a residential building, effective loads on design sections are given. Calculation of bases and foundations was carried out in accordance with regulatory documents for the first and second group of limit states.

At the end of the explanatory note, on the basis of a technical and economic comparison, the conclusion was made about the most economical version of the foundation.

In this version of the project, the option of a shallow foundation is more economically profitable.

SNiP 2.02.0183 Bases and foundations;

SNiP 2.02.0385 Pile foundations;

SNiP 2.03.0184 Concrete and reinforced concrete structures

Techno-economic comparison of foundation variants.

Technical and economic comparison of foundation variants is carried out in accordance with the recommendations. The technical and economic comparison in the course work is made for the maximum loaded section of the building of the administrative and domestic building. The comparison is made according to direct costs and labor costs in 1984 prices, taking into account the translation coefficient of excitement of the cost of work n = 15. Technical and economic comparison is presented in Table 5.1.
