摘　　要：在邻近水工建筑物环境下进行爆破开挖,爆破振动会产生一些负面效应,因此爆破振动监测十分必要。以大渡河深溪沟水电站安装间排水灌浆廊道开挖工程为例,对厂房机组及其他关键部位进行了爆破振动监测,并对数据进行回归分析,通过调整和优化爆破参数,既确保了原有机组的正常运行和其他水工建筑物的安全,同时又加快了工程施工进度,可为类似工程提供借鉴和参考。The blasting vibration monitoring is essential because of the negative effects on the adjacent hydraulic structures. Taking the drainage - grouting gallery excavation in the erecting bay of Shenxigou Hydropower Station as a case, the blasting vi- bration monitoring of powerhouse units and other key parts were analyzed. According to the regression analysis of monitoring data, the drilling and blasting parameters were revised and optimized. As a result, the powerhouse units operation and other hydraulic structures are protected from blasting vibration hazards, and the engineering construction progress is accelerated. The research a- chievement can provide reference for other similar projects.
