摘要：

The problem of the bearing capacity evaluation for a strip footing has been widely studied using theoretical and experimental approaches. This paper focuses on the bearing capacity of a strip footing on non-homogeneous clay. A series of numerical computations was carried out to evaluate the undrained bearing capacity of vertically loaded, rigid strip footing, using the finite element software PLAXIS 2D. The objective of this study is to analyse the effect of linearly increasing undrained shear strength with depth on the bearing capacity of a strip rough and smooth footing. The results of the present study are compared with those available in the literature. The values of the bearing capacity factor, obtained by the present analysis are in good agreement with the results calculated by the slip line method. It is confirmed that the correction factor is given as a function of dimensionless heterogeneity factor.
