Settlements and contact pressures of a nonlinearly deformable foundation bed subject to strip loading

Vyalov, S. S.

Conclusions 1. Consideration of the nonlinearity, creep, and mutual effect of the invariance of the stress tensor makes it possible to reflect more precisely the real properties of a soil and brings theoretical solutions in line with field data. 2. Nonlinearity, creep, and other factors can be accounted for in analytical solutions of the problem of the stress-strain state of a half plane, provided the laws satisfying conditions (5) and (7) are initial laws governing soil deformation. The general solution of this problem is given in the paper; however, selection of the specific form of law governing deformation is established on the basis of tests. 3. In the more general case — where the effect of the natural weight of the soil, variation in the type of stress state, the loading scheme and history, etc. are taken into account — solution of the problem is possible using an electronic computer. 4. The computational method under consideration can be used for practical bed designs, contributing to realization of the instructions in Construction Norms and Specifications II-15-74 concerning consideration, where necessary, of the nonlinear law governing the strain and creep of the bed soils.
