摘要
本文讨论了考虑饱和土壤固结效应的结构-土壤相互作用问题。利用子结构分析技术,将结构静力凝聚到与饱和土壤交界的界面上,建立结构-土壤体系变形-渗流过程的控制方程及相应边界和排水条件。文中给出了用于隐式-隐式逐步积分过程的改善的交错迭代求解方案及算法。本文工作巳在微机程序SACESS-J上实现。数值例题表明了结构变形和饱和土壤固结过程之间的藕合效应。
The soil-structure interactive analysis with the consideration of consolidation effects of the saturated soil is discussed in this paper. With the use of substructuring technique, the structure and the loads applied on it are condensed onto the interfaces between soil and structure, then the governing equation to describe the deformation-seepage process of soil-structure system with boundary and drained or undrained conditions are given. An improved staggered, iterative solution scheme and its corresponding algorithm for the implicit-implicit integration procedure of the governing equation are presented. The presented work has been implemented in a program SACESS-J for structure analysis with consideration of consolidation effects of saturated soil, which is developed based on existing program JIGFEX-W for structure analysis on micro-computers. Numerical results show the coupling effects between structure deformation and consolidation process of saturated soil.
