地下水渗漏对黄土隧道的围岩压力和物理力学性能变化、隧道正常安全运营及施工安全带来很大的影响。尤其是竣工后渗漏水,对工程的安全运营带来巨大的隐患。针对吴子高速公路黄土隧道的实际施工情况,对黄土隧道防排水施工的技术作了总结,并提出相应的质量管理措施,同时提高了防排水施工在黄土地区隧道建设重要性认识。
Groundwater seepage has a great impact on the pressure and physical and mechanical properties of the surrounding rock mass, the normal safe operation of the tunnel and the construction safety. Especially after the completion of the leakage of water, the project’s safe operation has brought huge risks. According to the actual construction of loess tunnel in Wuzi Expressway, the technology of drainage and drainage construction in loess tunnel is summarized, and corresponding quality management measures are put forward. At the same time, the importance of drainage and drainage construction in tunnel construction in loess area is enhanced.
