摘要:
对冻结法施工的地铁联络通道在融沉注浆后仍普遍存在的渗漏水现象，进行了总结归类。深入分析研究了渗漏水发生的各自原因，分别提出了前期预防措施及后期处置方法，并将其在多个联络通道施工中加以应用。工程实践检验表明，这些防漏措施及方法具有较好的工程效果及经济效益。
Abstracts:
In this paper, the widespread leakage water phenomenon in metro cross passage constructed with freezing method even after the thaw settlement grouting is summarized and classified. With an analysis of different water leakage reasons, the pro-phase prevention measures and the later disposal methods for the cross passage leakage are put forward, both methods are applied to multiple cross passage constructions. The engineering practices show that these measures have better engineering results and economic benefits.
