摘要
本文把土体弹塑性模型中已有的硬化理论归结为三种，即等值面理论、对偶应力理论和等价应力理论，并通过不同应力路线的数值计算对它们作了比较。
The existing hardening theories in elastoplastic model of soil are classified to three kinds,i.e.the isovalue surface theory,the dual stress theory,and the equivalent stress theory The comparisons are made among them with the help of numerical computation of different stress paths.
