非均质与各向异性临坡地基承载力上限计算

In order to provide an analysis method for the bearing capacity of strip footing adjacent to slop under condition of non-homogenous and anisotropy,combining with the unilateral sliding failure mode, the result of bearing capacity of strip footing adjacent to slop was obtained by using the method of upper bound limit analysis. Using Matlab software compile calculation program, taking the influence of non-homogeneous and anisotropy on the position and shape of failure face into consideration，then Nc'，the bearing capacity coefficient under non-homogenous and anisotropy was obtained.The results show that the solutions presented in this paper compaCalculation of Upper Limit Solution of Bearing Capacity of Non-homogeneous and Anisotropic Foundation Adjacent to Slopere reasonably well with the results in the existing literatures; it also can be seen that the influence of non-homogeneous and anisotropic on Nc' is revealed. Besides,when the failure mode converted to horizontal foundation, the results can also fit the results calculated by other methods tally well.
