摘要
小浪底泄洪、发电、引水等建筑物集中布置于左岸 ,该区域岩层软硬相间 ,各种结构面较为发育。通过对岩体各种可能滑动模式的稳定计算、有限元分析 ,并根据开挖施工中出现的具体情况 ,确定了对出口边坡采用以预应力锚索和抗滑桩为主的加固措施。施工中大量采用双层保护预应力锚索 ,在国内水利工程尚属首次。原型观测资料表明 ,处理效果好 ,边坡稳定。
The architectures of flood discharge, hydropower and water diversion were laid out on the left bank of the Xiaolangdi project. By many kinds of sliding mode stability calculation and finite element analysis of the rock body, they determined the outlet side slope strengthening measures mainly using prestressing anchors and resistance pile. The project was first one using prestressed anchors with double layer protect for construction in domestic hydraulic engineering. The prototype observation data proved that the procession effect is well and the side slope is stable.
