The finite element method of solving engineering precipitation falling curve based on seepage principle

在渗流基本原理的基础上提出利用三角形相似求解稳定潜水井的基坑降水降落曲线的有限单元法。采用该方法计算了实际工程案例的降落曲线,并与解析解和实测值作了对比,结果表明该计算方法更接近实测值。该方法可为基坑工程等降水工程的地下水控制设计提供依据。

Based on the basic principle of seepage,this paper presents a finite element method to solve the dewatering falling curve of the foundation pit of the stable diving well by using the triangle similarity.The method is used to calculate the landing curve of a practical engineering case,and compared with the analytical solution and the measured value.The results show that the calculation method in this paper is closer to the measured value.This method can provide basis for groundwater control design of foundation pit and other dewatering projects.
