| 摘 要： | 采用三维有限元方法分析了基坑开挖工程在防渗体出现局部失效情况下，引起渗流在失效部位的集中及渗流场空间状况。提出了以一维通道嵌入三维块体的方法模拟管涌发展过程及渗流场变化特征。讨论了管涌通道渗透性对基坑管涌发展规律的影响。

| Abstract: | With 3-dimensional FEM method, seepage field of pit excavation case of local breakage in seepage proof wall were put to study. In this paper, method of embedding piping tunnel in 3-dimensional block is put forward to simulate piping erosion process. The effect of piping conductivity in the piping development process was taken into discussion. |
