爆破振动对邻近水工建筑物影响的监测与分析

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。 

Monitoring and analysis of influence of blasting vibration on adjacent hydraulic structures

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 vibration 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 achievement can provide reference for other similar projects. 
