【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.更多还原
