锦屏水电枢纽辅助洞(B洞)高压水处理施工技术

Tackling the high pressure ground water in the access tunnel of Jinping Hydro-electric Plant

锦屏水电枢纽工程是一项大型的水电工程,它的建设将为国家特别是西部的电力行业做出巨大贡献,该水电枢纽辅助洞工程是水电站前期工程的控制性关键项目。文章介绍了施工中遇到的高压涌突水问题,以及根据不同的地质和涌突水情况确定的不同处理措施,可为今后解决类似的工程问题提供借鉴和参考。

The access tunnel project is the key item in the preliminary phase of the construction of Jinping Hydro - electric Plant. The paper introduces the high pressure ground water ingress and outburst encountered in the construction and different countermeasures employed to tackle them according to the different geological and ingress and outburst conditions, which can be taken for reference by similar projects.
