| 摘 要： | 根据确定岩石爆破中爆源近区的质点峰值震动速度衰减规律的波动方法，导出了岩石爆破中岩体损伤范围的计算式。结合岩体爆破损伤的质点峰值震动速度安全判据，就龙滩水电站右岸导流洞爆破开挖工程中岩体损伤范围进行了计算，并对理论计算结果与围岩损伤范围的声波法检测结果进行了对比与分析。

| Abstract: | Depending on the method based on the stress wave theory to calculate the peak particle velocity(PPV) induced by blasting,an equation to calculate the blast-induced damage zone in rockmass is educed. In accordance with the PPV criteria for blast-induced damage, the blast-induced damage zone is calculated for the blasting excavation of the diversion tunnel at the right bank of Longtan Hydroelectric Project. Analysis and comparison between results of the calculated and measured blast-induced damage zone with method of sonic measurement are presented. |

| Keywords: | Longtan Hydroelectric Project blast-induced damage zone peak particle vibration velocity |
