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,引起爆裂松脱、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。对某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,提出了防治措施,为工程顺利实施提供先决条件。
Rock burst is destruction phenomenon of burst loose,peeling and catapult,which caused by the violent release under the condition of elastic deformation potential aggregating inside rock.It is a common geological disaster after digging ultra-deep tunnel that threaten the safty of person and equipment.This paper analyzes the forming conditions and forecast methods of tunnel rock burst about a hydropower station to determine the classification of rock burst intensity and prevention measures.
