【摘要】 本文对锦屏二级水电站引水隧洞在前期试验硐施工建设过程中遇到的工程地质问题(高地应力岩爆与岩溶涌突水)进行了分析研究。概述了锦屏二级水电站引水隧洞地应力场、岩爆及其监测预报的情况,并对隧洞岩溶涌突水的特征、原因及其对隧洞的影响进行了分析研究;提出了岩爆和涌突水的防治措施,并在数值计算的基础上在工程中予以实施,取得了良好的效果。为同类地区的隧洞施工提供了借鉴。更多还原

【Abstract】 In this paper,the authors have studied the high-stress rock burst and water outburst occurred in experimentation tunnels of Jinping waterpower station separately.The ground stress surveying, rockburst and surrounding rock monitoring prediction in experimentation tunnel were mentioned,then study of the characteristics,influence factors of water outburst in tunnel are presented.Some prevention-measures against rock burst and water outburst are proposed.These measures were used in practice and obtained some good results.Some suggestions for the construction of diversion tunnel with hige stress and high groundwater were presented.更多还原
