摘要： 富水软弱地层深基坑施工期间的涌水问题一直是工程界的一大难题。以某临海软弱富水区工作井基坑涌水为案例，从基坑工程的地质、施工等方面总结了此涌水的成因，通过对涌水事件整个过程的分析，给出了临海软弱富水地层涌水防治措施的思考及总结，以期对类似工程的设计和施工提供参考。

Abstract: It is a common and challenge hazard of the groundwater gushing from the water enriched weak soil strata during the deep excavation. This paper presents an engineering case study of the treatment of groundwater gushing during a vertical shaft excavation in the coastal soft soil areas. The aspects that might potentially affect the groundwater gushing, such as, specific site conditions, special construction methods and sequences are also discussed in the paper. Summaries in the deep excavation are provided with the aim of providing references for the future constructions in the similar areas.
