基于LEC风险评价方法的水工隧洞爆破施工危险源辨识及安全评价

Hazard Source Identification and Safety Evaluation of Hydraulic Tunnel Blasting Construction Based on LEC Risk Assessment Method

水工隧洞施工普遍采用爆破技术,工序多、作业环境复杂,危险源众多,使用LEC风险评价方法可分析各类风险因素并加以计算,从而得出风险分值,并根据风险分值对风险加以分级,有利于施工现场安全生产管理,给安全顺利施工带来有力保障。

Blasting technology is widely used in hydraulic tunnel construction,with many working procedures,complex operation environments,and numerous hazard sources.LEC risk assessment method can be used to analyze various factors and calculate,so as to obtain risk scores and classify the risks according to the risk scores,which is conducive to safety production management at the construction site and provides a strong guarantee for safety and smooth construction.
