摘要
针对高海拔高寒地区隧道施工过程中受反复冻融影响产生的渗漏水危害展开研究,在这一特殊地质条件下富水隧道中防排水的施工技术研究中,与普通隧道相比,渗漏水是隧道施工和营运期主要病害之一,易造成二衬开裂和渗水,从而影响其结构和行车安全。本文以花石峡至久治公路雪山1号隧道工程实例,对隧道富水段的的主要处理技术及集中出水段综合治理措施进行深入研究,通过反复探讨和论证,优化施工方案,完善防排水体系,研究结果表明采取有效的技术措施可避免隧道受到渗漏水的侵害,治水效果良好,可为类似隧道工程施工提供一定的参考。
Seepage is one of the major diseases during tunnel construction and operation, compared with ordi- nary tunnels, the tunnels in high altitude and cold regions are extremely prone to freeze - thaw cycles, so that the tunnels could be damaged by seepage water, and occur second lining cracking and seepage, these would affect the structure and traffic safety. Such problems are generally caused by careless construction details, and there is no strict quality controlling, so it should understand the design intent, strongly grasp the control of quality, ensure the waterproof and drainage of the tunnels. According to the project of No. 1 tunnel in Xueshixia to Jiuzhi Highway, this thesis explains the key points and precautions of waterproofing and drainage construction, through repeated research and demonstration, the construction scheme is optimized and effective measures are taken to prevent the tunnel from being infihrated by water.
