摘　　要：金河四级水电站厂房后边坡最大坡高约55m，但由于处于三家河断裂破碎带和影响带内，节理裂隙发育，岩体破碎，开挖边坡稳定条件较差。开挖完成后边坡两次出现大范围裂缝，根据现场情况，及时采取了有效的加固支护措施。电站于2006年正式投入运行，经监测边坡一直处于稳定状态，说明加固支护措施合适。The maximum height of the side slope behind the powerhouse of Jinhe-4 Hydropower Station is about 55m high. It is located in Sanjia River fault zone and its influence zone, and it also has developed fissure and cracked rock. The stability of slope is very bad. Large-scale cracks appeared twice after the completion of excavation. According to the site situation, the effective supporting measures were promptly taken. The commissioning of the Hydropower Station was in the year of 2006. Monitoring suggests the side slope is stable from then on, which means supporting measures are reasonable.
