某水电站二期工程地下洞室开挖爆破震动风险分析

Risk Analysis on Blasting Vibration during Underground Cavern Excavation in The Second Stage Construction at One Hydropower Station

结合某水电站二期工程地下洞室的开挖爆破,对影响爆破震动效应的风险变量进行了分析。利用现场开挖爆破震动试验所取得的数据,通过对风险变量的预测,用蒙特卡洛模拟(MC)法评估其爆破震动风险。

Risk Analysis on variations which affect blasting vibration effect is conducted according to one underground cavern excavation and blasting . The field test data from excavation and blasting vibration are used to predict risk variations and the Monte Carte(MC) method is adopted to estimate the blasting vibration risk .
