摘要介绍深井降水条件下,考虑土体粘弹性压密特征和土-水耦合作用的深基坑渗流场分析模型。在此基础上,运用有限元方法对其进行数值模拟。为提高计算精度,对含水层非饱和带和自由面问题进行了适当考虑。设计了基于Microsoft Windows 95/98/NT平台的面向对象有限元软件,给出了基本的程序框架和有关的程序段。
Abstract:Under the condition of pumping water from the deep well point,the viscoelastic flow model in deep excavation is proposed to consider the three-dimensional deformation of the viscoelastic compaction of the soil skeleton of aquifer due to pumping and coupling influence of soil-water. Furthermore,on the basis of the model,numerical simulation with FEM is used. In order to improve computing precision,unsaturated zone and unconfined flow are taken into consideration. In addition,an object-oriented FEM software based on Microsoft Windows 95/98/NT is developed. The basic program frame and main codes are given.
