基坑工程中应力场与渗流场直接耦合的有限元法

THE FINITE ELEMENT METHOD OF DIRECT COUPLING BETWEEN THE STRESS FIELD AND THE SEEPAGE FIELD OF FOUNDATION PIT PROJECTS

根据虚位移原理推导出基坑渗流直接耦合法的有限元公式 ,针对直接耦合法所生成的病态方程编写出基于MATLAB环境的有限元计算程序。

Based on the virtual displacement principle, the paper derives Aiming at the abnormal equations produced from the direct coupling method, the FEM computing programme based on the MATLAB environ ment is compiled The computing result of foundation pit coupling model manifests the stability and feasibility of the programme to solve the abnormal equations.
