| 摘 要： | 东风水电站右坝肩边坡加固处理采用了全锚索处理方案,锚索平均深度约70 m,最深为92 m。由于坝肩岩体卸荷裂隙发育、溶蚀现象严重,施工中存在100 m级高排架施工难、成孔难、孔斜控制难、注浆难等诸多技术难题,通过对深孔预应力锚索施工技术进行攻关研究,使得工程加固处理得以顺利实施。其施工经验值得在喀期特地区类似边坡的加固处理中推广应用。

| Abstract: | The treatment scheme with full anchorage cable was adopted in reinforcement treatment on the right abutment of Dongfeng Hydropower Station.The average depth of anchorage cable is about 70 m and the most depth is 92 m.Due to the well development and serious corrosion of unloading fissures of abutment rock mass,there are some technological problems,such as hard construction of high bent with 100 m grade,hard forming hole,hard controlling hole inclination,hard grouting,and so on.Through studied the key construction technology of pre-stressed anchorage cable with deep-hole,the reinforcement treatment was implemented successfully.The construction experience is worth popularizing to similar slope reinforcement treatment in Karst areas. |
