摘　　要：东江水电站引水工程取水口、引水隧洞施工支洞距已建大坝、右坝肩、厂房、开关站、二级放空洞、坝基帷幕等较近,其爆破施工可能对大坝及其附属建筑物的安全和电站的正常运行造成影响。为此,进行了右岸岩体和坝体爆破振动衰减规律测试、水下冲击波测试等试验,以在施工中合理控制爆破振动。Because the intake of water diversion project and the construction drift of diversion tunnel is closer to built dam, right dam abutment, powerhouse, switching station, secondary discharge outlet and dam foundation curtain, the blasting of water diversion intake and drift may affect the safety of dam and auxiliary structures and the normal operation of powerhouse. To this end, the tests of blasting vibration attenuation in right bank rock mass and dam and underwater shock wave are conducted to control blasting vibration reasonably in construction.
