3000KN预应力锚索在广西桥巩水电站船闸工程的应用

Application of 3000KN Prestressed Cable Lock in Guangxi Qiaogong Hydropower Project

预应力锚索主要是通过锚索将软弱松动、不稳定的岩土体悬吊在深层稳定的岩土体上,以防止其离层滑脱,从而提高边坡岩土的整体性和稳定性。桥巩水电站船闸闸室3～6段左侧边坡地质条件复杂,存在软弱夹层,为保证左侧闸墙的整体稳定和工程的长期运行安全,施工中对该段进行了3000kN级预应力锚索加固措施。文章对船闸预应力锚索施工进行了阐述。

Prestressed cable lock is mainly through cable lock suspends at the loose and unstable rock and soil on the deep and stable rock body,in order to prevent their separation slip,and to enhance enhancing the integrity and stability of rock slope.From 3 to 6 on the left slope of the ship lock at Qiaogong hydropower station have complex geological conditions,and there is soft interlayer.So to ensure the overall stability of the left lock wall and the long-term safe operation of the project,in the construction of the section used 3000kN level Prestressed cable lock reinforcement measure.This article describes the prestressed cable lock construction.
