Ultimate bearing capacity of shallow footing on anisotropic and nonhomogeneous clays

By use of the upper limit theorem of plastic limit analysis and variational principle,the ultimate bearing capacity of anisotropic and non-homogeneous foundation soils were ascertained,and the basic formulas were derived.It was analyzed with the computation program how the anisotropic and non-homogeneous parameters influenced the bearing capacity.The results were compared with other scholar’s results.It was shown that the bearing capacity obtained by this method was more reliable.
