隧道施工一直是土木建筑工程中工程量大、技术难点多的一项工程分类,而在隧道施工的诸多技术难点中,在施工过程中如何保证防水排水的措施工作实施成功是关键点,本文就如何在一些复杂环境,如丰富的地下水和降水地区、围岩地质脆弱等不利施工的情况下开展防水排水的工程。 Tunnel construction has been an engineering classification of civil engineering projects with large amount of engineering and technical difficulties. Among the many technical difficulties in tunnel construction, it is the key point to ensure the successful implementation of waterproof and drainage measures in the construction process How to carry out waterproofing and drainage works in some complex environments, such as abundant groundwater and precipitation areas and the fragile surrounding rock geology.
