摘要

锦屏Ⅱ水电站辅助洞是典型的深埋隧洞，高应力条件下的岩爆灾害一直是设计和施工阶段面临的主要问题之一。通过统计辅助洞开挖过程中岩爆的基本规律，结合地应力和典型岩层的室内岩石力学试验，采用不同的岩爆评价指标对辅助洞的岩爆危险性进行了评价分析。并针对辅助洞工程的实际情况，讨论了施工过程中岩爆防治的措施，提出相应的岩爆控制对策，为锦屏Ⅱ水电站正在施工的4条深埋长大引水隧洞中岩爆的预测和防治提供了重要的基础性数据和借鉴，并可为现场施工提供指导

Abstract

Auxiliary tunnels of Jinping Ⅱ hydropower station are deeply buried. Rock burst under high geo-stress is one of the main problems to be taken into account. With the statistical data of the rock burst in the auxiliary tunnels and the in-situ stress and the mechanical properties of the rock

risk of rock burst in the auxiliary tunnels is analyzed by using different indexes. In addition

the prevention and cure methods of rock burst in the auxiliary tunnels are discussed. The results can provide basic support for rock burst estimation and prevention in the process of construction of four diversion tunnels in Jinping Ⅱ hydropower station.
