| 摘 要： | 招徕河水电站坝址处地形陡峻 ,地质条件复杂 ,左坝肩高程 2 60m以上采取了窑洞式的开挖方式 ,并采用预应力锚索对由于纵、横向裂隙切割及坝肩开挖形成的不稳定岩体进行了加固处理。实践证明 :这种窑洞式开挖方式对减轻生态环境的破坏 ,缩短施工工期 ,降低工程造价和提高坝肩稳定性都十分有效 ,值得在狭窄河谷拱坝坝肩开挖中借鉴。

| Abstract: | Zhaolaihe arch dam is situated in a precipitous valley with complex geological conditions, the neighboring rock mass of left abutment above El260 m is excavated with cave-dwelling type rock cut method, the fissured and unstable rock mass is strengthened by prestressed cables, therefore, the damage on environment is lightened, the construction period is shortened, the stability of left abutment is improved and the construction expenses is cut down. |
