摘要
金河水电站厂房后边坡覆盖层深30m左右,岩石强风化,卸荷强烈,稳定性较差,为保证边坡在开挖及电站运行过程中的安全稳定,设计采用2000kN级预应力锚索进行加固处理。根据工程特点和对比分析,预应力锚索型式采用自由式拉压复合型预应力锚索,该类型锚索首次在西藏昌都地区使用,效果显著。
The covering depth of the back side slope of the power house in Jinhe Hydropower station is about 30 m,the rocks & stones are strongly weathered and c an't be loaded with weak stability. 2000 KN grade prestressed anchor cable was adopted in design for fixing and reforcing to ensure the safty during side slope excavation and operation of the power station. Free type pulling & pressing pre stressed anchor cable were used accoording to the characteristic of this project and comparative analysis,this kind of anchor cable is used in Changdu area,Tib et for the first time and remarkable effect is seen consequently.
