摘要
为发展一个实用的土壤固结非线性有限元分析程序,在以往工作的基础上,以变分原理为基础,给出了饱和土壤固结弹塑性分析的基本方程.利用文中的理论,编制了有限元通用分析程序DIASS,并进行了例题计算.对考虑非线性弹性与弹粘塑性模型的土体固结分析方法进行了讨论.
The purpose of this work is to develop a general nonlinear analysis program for soil consolidation. Based on variational principle, the fundamental equations are put forward for consolidation analysis of elasto-plastic saturated soil. A general analysis program DIASS has been developed in terms of the theory given. The computational methods dealing with nonlinear elastic and elasto-visco-plastic constitutive model of soil are discussed.
