在深基础施工中，由于地下水文、地质情况的复杂性，经常会碰到管涌等不利情况的发生，一旦形成管涌之后，管涌的泛水点迅速由小变大而使基础积水、泛砂，给施工带来不利影响。本文通过杭州下沙某项目在基础施工过程中发生管涌现象的分析，阐述了深基坑内管涌现象的成因及其处理对策。

In the construction of deep foundation, because of the complexity of groundwater hydrology and geology, there is often the occurrence of adverse circumstances piping. The fo-rmation of piping will make the piping flashing point rapidly change from small to big and make the water and sand form in the foundation, and bring bad influence to the construction. In this paper, based on analysis of piping phenomenon in the process of construction of a project in Xiasha in Hangzhou city, expounds the causes and treatment countermeasures of piping phenomenon in deep foundation pit.
