Abstract
1. The method presented in Construction Norm and Regulation (SNiP) 2.02.01-83 for the computation of foundation settlements does not take into account the effect of redistribution of the stress-strain state of the bed as a result of trench excavation, and does not therefore reflect the actual behavior of the bed beneath the structure. Thus, the settlement may be equal to zero, or even negative for a deep embedment. 2. The proposed computational scheme, which is based on expansion of the existing method by the supplementary construction of softening-pressure curves using attenuation factors obtained on the basis of theoretical solutions, makes it possible to compute settlements with allowance for bilinear deformability of bed soils, and the shapes and sizes of the trench and foundation.
