响洪甸大坝为87.5m高的重力拱坝,抽水蓄能电站的进水口位于其上游200多m处,采用水下岩塞爆破形成.为确保大坝的安全,在岩塞爆破前做过两次爆破试验,正式爆破时又委托中国地震局工程力学研究所进行爆破振动和水冲击波的监测,同时响洪甸电站水工科也组织人员加强了对大坝的常规观
Xiang Hongdian dam is a 87.5m-high gravity arch dam, and the water intake of the pumped-storage power station is located at 200 m upstream of it, and is formed by underwater rock burst. To ensure the safety of the dam, After two blasting tests, the official blasting commissioned the Institute of Engineering Mechanics, China Earthquake Administration to carry out blasting vibration and water shock wave monitoring. At the same time, the engineering department of Xianghongdian Hydropower Engineering Branch also organized personnel to strengthen the conventional view of the dam
