透水是城市地铁施工过程中易发生的事故类型之一。论文选用专家调查法和事故树分析法对城市地铁施工过程中的透水事故进行分析，计算出顶上事件的最小割集、最小径集和发生概率。并根据原因事件概率和临界重要度的计算，得出底板防水失效是引起透水事故发生的主要原因事件，因此地铁施工过程应对其加强监督与管理，从根本上预防透水事故的发生。

Flooding is one of the accidents which is easily occurred during city metro construction. This paper analyzes the flooding accidents during metro construction with expert investigation and fault tree analysis methods, calculates the minimal cut sets, path sets and probability, and puts forward that the floor waterproofing failure is the main cause according to calculating the probability and critical importance, so it must be strengthened with supervision and management during metro construction, to prevent flooding accident radically.
