岩溶地区隧道的排水设计及施工关键技术

Drainage Design of Tunnel in Karst Area and Key Technologies for Construction

中国西南山区近期面临大量的长大岩溶隧道修建问题,针对其设计、施工的特殊性以及特殊季节,就岩溶隧道施工关键技术和方法进行深入探讨,并提出水是岩溶隧道所有问题的诱因和主因,进一步指出如何做好岩溶隧道的防排水施工,以最大程度地避免地质灾害的发生,提高岩溶隧道的施工技术水平,讨论结果对类似工程具有指导意义。

A large number of karst tunnels have been built recently in the southwestern mountainous area of China. In view of the design, construction and seasonal effect, key technologies and methods for the construction of tunnels in karst area were discussed in depth. It was proposed that water is the main cause of all problems in karst tunnels. It is further pointed out how to do well in waterproofing and drainage construction of karst tunnels to avoid the occurrence of geological disasters to the greatest extent and improve the construction technology level of karst tunnels. The results of the discussion are instructive for similar projects.
