摘要:: 文章以某高速铁路11 km长的明挖全包防水隧道为依托，对全包防水隧道渗漏水出现的部位进行了统计，统计结果表明，全包防水隧道渗漏主要分布于施工缝、变形缝及衬砌有质量缺陷的部位。通过对渗漏特点及渗漏部位结构、施工过程、施工工艺的研究，得出全包防水隧道渗漏水的主要原因。结合该工程渗漏水治理经验，提出"以堵为主、堵排结合、分区治理"的原则，总结了一套较为有效的渗漏治理措施，可为今后类似工程提供参考。

Abstract:: Taking 11 km open-cut fully wrapped waterproofing tunnels of high-speed railway as an example, the leakage location of fully wrapped waterproofing tunnels is statistically analyzed, The statistical results show that the leakage mainly locates on construction construction joints, deformation joints and the location which has mass defect on tunnel lining. By the research of the leakage characteristic and the structure, construction process, construction technology of the corresponding location, the main reason of leakage is obtained. Combined with the leakage treatment experience, the design principle of Mainly blocking up, combining with blocking and drainage and division harness is put forward, and a set of effective leakage control measures are concluded, which can provide reference for the similar projects in future.
