Abstract
Traditionally, the formulas of critical edge pressure pcr and critical load p1/4 are developed by assuming coefficient of earth pressure at rest K0 equal 1. It means that the geostatic stress is treated as hydrostatic stress. This assumption leads to an increase in lateral load of subsoil and results in a higher bearing capacity of subsoil. In the paper, a MATLAB program is used to find the numerical solution of bearing capacity of soil for K0 ≠ 1. The proposed method overcomes some shortcomings of the methods available in the literature for K0 ≠ 1. The influence of shear strength parameters of soil on the critical load is investigated.
