摘要
本文应用笔者此前所提出的粒状材料强度异向性规律的理论表示式和异向性粒状体的ｋｔｔｅｒ塑性应力场方程式，将浅基极限承载力的Ｐｒａｎｄｔｌ－Ｒｅｉｓｓｎｅｒ理论解（γ＝０）和Ｃｏｋｏ数值解（γ≠０）拓展到异向性粒状土地基中。这些结果都可表示为不依赖于强度参量ｔｇψ（ζ）的具体假定形式的一般形式；这些结果还都已设定成在必要时可按拟静法考虑水平地震荷载效应的形式。
In this paper Prandtl-Reissuer's theoretical solution (γ =0) and Sokolovsky's numerical solution (γ≠0) about bearing capacity of shallow foundation for isotropic granular soils have been extended to anisotropic ones, by applying the theoretical expression about the rule of strength-anisotropy for granular materials and Ktter's equation of plastic stress field for anisotropic granular mass, suggested by the author before now. Moreover, these results can be all expressed as a general form which is independent of specifically assumed form of strength parameter tgψ(ζ), and they also have been set as a form, in case of necessity, that can be considered as the effect of horizontal earthquake force using the analogous static method.
