洪家渡水电站左坝肩高边坡预应力锚索试验分析

洪家渡水电站左坝肩边坡开挖高度达 310m ,是中国水利水电工程史上开挖最高的边坡。为确保边坡稳定 ,设计采用了 15 0t级预应力锚索加固措施。在锚索大规模施工之前 ,先进行了预应力锚索锚固试验 ,以确定和优化初步拟定的锚索设计参数、检验各配套材料及已定施工工艺的可行性等

Test Analysis of Pre-stress Anchor Cable in High Side on The Left Abutment of Hongjiadu Hydropower Station

Excavation height on the left abutment of Hongjiadu Hydropower Station is 310 m, the highest excavation side in conservancy and hydropower engineering history of China, In order to ensure stability of the high side, the pre stress with 150 t anchor cables are used as a reinforcement measure. Before construction of the cables in large scale, the anchor test of the pre stress anchor cables was conducted for the purposes of defining and optimizing the design parameters of the anchor cable will be used, examining the feasibility of various corollary materials and construction process will be adopted.
