Abstract
Accurate analyses of foundation seepage field and prediction of seepage flow of drainage wells are important for reasonably arranging drainage system of foundation engineering and maintaining the stability of foundation pit as well as the safety of engineering.According to the needs of actual engineering,the calculation method based on 3D FEM is used for analyzing the seepage flow of a certain profile.A numerical method to compute the displacement of complex foundation pit is also proposed by using arbitrary cylindrical mesh wells.A computer code for counting the seepage flow of pit drainage wells is developed based on FEM and has been applied to the calculation and analyses of drainage flow in the foundation pit excavation of a hydropower station.The results show that the method has good applicability and accuracy.关键词
