异向性粒状体的极限平衡理论

Limit Eguilibrium Theory for Anisotropic Granular Mass

本文以笔者提出的粒状材料强度异向性规律的理论表示式￣［１，２］为数学手段，推导了可适用于异向性粒状体的Ｋｏｔｔｅｒ塑性应力场方程，阐明了这种塑性应力场的基本特征。这一结果，可以表示为不依赖于强度参数ｔｇψ（ζ）具体假定形式的一般形式，而且还已假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 Kottter′s equation of plastic stress fidld and its characteristics have been derivedand expounded for the anisotropic granular mass by means of the theoretical expression for the rule ofstrength-anisotropy for granular material,suggested by the author before. Moreovethis result can beexpressed in a general form independent of the assumed strength parameter ,and it also has beenso set that,in case of necessity,the effect of horizontai earthquake force can be considered by thepseudo-static method.
