Popis: 1. In designing natural foundation beds with layers of weak clayey soils, the final settlements of the foundations and the settlements with time can be computed using the theories of elasticity and seepage consolidation in accordance with the method outlined in the paper. This is confirmed when additional (over and above the natural) pressure p0 ≤ 5c are applied to the top of the weak clays, where c is the minimum specific cohesion of the clayey soils as determined with allowance for the possible reduction in cohesion with time. When p0 > 5c, including pressures on the roof of the weak clays equal to the design pressures given in Section 3.62 of SNiP II-15-74, there are only isolated cases of building construction from which it is impossible to judge laws governing bed deformation. 2. In conformity with Section 1, the method of computation clarifies the computation of settlements as compared with SNiP II-15-74, simplifying the design of beds with layers of weak clayey soils.
