摘要
乌东德水电站是国内第四、世界第七大水电站,坝址区河谷高、陡、窄的特征十分显著,给开挖施工带来了极大挑战。为实现大坝边坡和建基面精细开挖,从施工工艺、爆破技术、施工安全和精细化管理等方面对开挖技术进行研究,形成了适用于陡倾岩层复杂地质条件下的边坡和建基面精细开挖技术,并在乌东德水电站成功应用,具有较好的借鉴意义。
Wudongdong hydropower station will be China’s fourth largest and the world’s seventh largest hydropower project upon completion.The valley in dam site area is marked by its features of high,steep and narrow,which brought great challenge to excavation construction.To complete the excavation of dam slope and foundation surface elaborately,excavation technology was studied in construction techniques,blasting techniques,construction safety,refined management and other aspects.Elaborate excavation technology of slope and foundation surface has been formed,which can be suitable for steep rock strata and complicated geological conditions.It has been successfully applied in Wudongde hydropower station and has strong reference significance in other similar projects.
