摘要
Rock burst in rock mass is a kind of gathered the elastic deformation of potential energy in certain conditions of the violent,and cause sudden release including the blowout loose,stripping,and even throwing damage phenomenon of ejection,is common geological disaster after buried deep tunnel excavation.It greatly threatens construction safety of people and equipment.In this paper,the authors analyze basic conditions,prediction method of the formation of the rock burst in RuHe basin Muxingtu hydropower station in Shangri-la county,Yunnan Province,discriminate intensity level of rock burst,put forward the prevention measures.
