摘　　要：均质土坝渗流分析的水力学方法比较简单实用,同时也具有一定的精度,但该方法的难点为求解非线性方程。以某均质土坝为例,编写MATLAB程序,实现非线性方程的Newton迭代法求解。通过对上述计算成果与理正岩土渗流分析软件计算成果进行比较,对成果的差异性进行分析,并给出建议。The hydraulic method to seepage analysis of homogeneous earth dam is more simple and practicable.At the same time,it also has certain precision.But the difficulty of this method is to solve the nonlinear equation.In this paper,we used a homogeneous earth dam as an example to write program in MATLAB,which realizes solving nonlinear equations by Newton iteration method.By comparing the above calculation results with the calculation results of leading geotechnical seepage analysis software,the differences of the results were analyzed and relevant suggestions were provided.
