摘　　要：结合工程实例,对软土地层盾构区间在盾构进出洞施工中遇到的渗漏水情况进行了分析。总结了渗漏水产生的原因,并对渗漏水的来源作出了判断。通过优化加固形式和及时增加冻结加固,避免了后期同样工况下出现渗漏水的现象,总结的经验可为类似工程提供参考。Combined with an engineering example,the water leakage encountered in the construction of shield machine in and out of tunnel well in soft soil stratum was analyzed.The causes of water leakage were summarized,and the source of water leakage was evaluated.By optimizing the reinforcement form and adding freezing reinforcement in time,the phenomenon of water leakage under the same working condition in the later stage was avoided.The summarized experience can provide reference for similar projects.
