摘　　要：从分析基坑中发生突涌的机制出发，运用弹性薄板理论，探讨了在不满足压力平衡条件下进行施工时，基坑突涌的验算问题；推导出了判别矩形基坑是否由于剪切破坏或挠曲破坏而发生突涌的判别式。This paper analyses the piping principle of foundation pit.According to the theory of elastic thin plate,the problem abount the piping check computation of foundation pit during the construction proceeded under the condition without pressure equilibrium is discussed.The discriminant used to judege whether the piping in rectanglar foundation pit is induced by shear failure and deflection failure deduced.
