ANALYSIS OF ULTIMATE BEARING CAPACITY FACTOR OF BURIED STRIP FOUNDATION ADJACENTTO SLOPE BASED ON TERZAGHI THEORY OF FOUNDATION ULTIMATE BEARING CAPACITY

摘要

Considering the contribution of soil strength after the slope to the ultimate bearing capacity of foundation adjacent to slope,the strength of soil after the slope was reduced,and the reduction factor m was used to characterize its strength.A bilateral asymmetric slip failure model was established.Based on Terzaghi theory of foundation,the ultimate bearing capacity of buried strip foundation adjacent to slope was divided into three parts,represented by three bearing capacity factors Nr,Nq,and Nc.Based on the condition that the triangular elastic wedge under the foundation should satisfy the static equilibrium equation,a trial algorithm was used to obtain the value of m,and the expressions for three bearing capacity factors were obtained.The effect of multiple parameters on the three bearing capacity factors of buried strip foundation adjacent to slope was analyzed through programming calculations.
