基于广义Ｂｉｏｔ理论对土体弹塑性团结过程进行求解，建立了问题对应的参变量变分理论，并给出了数学证明。在此基础上推导了有限元分析列式，问题的求解最终化为参数二次规划问题。本文提出的方法适用于固结弹塑性分析的关联与非关联流动问题，也可处理各类软化问题。 Based on the generalized Biot theory, the elastoplastic solidification process of soil is solved. The variational theory of parametric variability is established and the mathematical proof is given. On the basis of this, the finite element analysis is deduced, and the solution of the problem is finally solved as the parameter quadratic programming problem. The proposed method is suitable for both associated and unassociated flow problems in consolidation elasto-plastic analysis as well as for various types of softening problems.
