摘要
岩爆是一种岩体中聚集的弹性变形势能在一定条件下的突然猛烈释放,从而引起的爆裂松脱、剥离、弹射乃至抛掷性破坏现象,是深埋大长隧洞在开挖后常见的一种地质灾害,极大地威胁着施工人员和设备的安全。以云南省香格里拉县尼汝河流域木星土水电站引水隧洞岩爆形成的基本条件、预测预报方法进行分析,从而判别岩爆烈度级别,并提出了防治措施,为工程顺利实施提供先决条件。
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.
