重点以圆梁山高水压岩溶富水隧道为对象，通过圆梁山隧道背、向斜岩溶水处理和溶洞的防水施工实践，并结合重庆万开高速公路铁峰山岩溶隧道防水实际，从岩溶水处理、溶洞处理、高压富水段施工防水处理等方面对岩溶隧道施工防水原则、施工方法选择和施工技术进行了探讨，希望能为类似隧道的施工防水提供借鉴。

On basis of the practice of the treatment of the karst water in the anticline and syncline structures and the waterproofing construction of Yuanliangshan tunnel and the practice of waterproofing construction of Tiefengshan karst tunnel on Wankai highway in Chongqing, the article describes the treatment of karst water and karst caves and the waterproofing construction of the tunnel portion with huge volume of highpressured water and makes discussions on the principles of waterproofing construction, the selection of construction methods and the construction techniques of karst tunnels with high water pressures, which can provide reference for the construction of similar tunnels.
