Abstract:

The paper describes the special features of the calculation based on the load-bearing capacity of soil loaded with strip-shell foundations which offer high efficiency in construction of medium and high-rise buildings on strongly compressible soils. The necessity of this calculation is caused by the requirements of Building Regulations. Problem solution of load-bearing capacity of subsoil with a bent cylindric surface based on the known Prandtl Solution was considered. The new static solution to the Coulomb's wedge theory of load-bearing capacity of soil loaded with strip-shell foundations (SSF) indicating that taking into account a bent surface of the soil under the shell and the counterweight from strip foundations make it possible to reasonably increase the load-bearing capacity of soil.
