张峰水库溢洪道闸室预应力锚索施工

Construction of Prestressed Anchorage Cable on Sluice Chamber of Zhangfeng Reservoir’s Spillway

张峰水库溢洪道闸室底部存在软弱夹层,对地基稳定不利,设计单位采用预应力锚索进行加固处理,以提高其抗滑稳定性。文中对预应力锚索从施工参数的确定,到施工的每个环节进行了详细的阐述。

The soft interlayer exists under the bottom of sluice chamber of Zhangfeng Reservoir＇s spillway. It is unfavorable for foundation stability. The design unit adopts prestressed anchorage cable to carry out consolidation treatment so as to raise stability against sliding of sluice chamber. The article in detail introduces the determination of construction parameters of prestressed anchorage cable and every link in construction process.
