世界上首次将锚索技术运用于水电工程的时间在20世纪30年代,我国的锚索加固技术始于60年代。从70年代开始,该项技术在我国水电等领域开始逐步得到使用。在滑坡治理工程中,预应力锚索通过预应力的施加,增强滑带的法向应力和减少滑体下滑力,有效地增强滑坡体的稳定性。本文介绍了预应力锚索施工方法、施工工艺流程,通过合理安排施工顺序,加快了施工进度,保证了施工质量,确保了资源的优化利用。
The world’s first anchor technology used in hydropower project time in the 1930s, China’s anchor reinforcement technology began in the 60’s. Since the 1970s, the technology began to be used gradually in fields such as hydropower in our country. In the landslide control project, the prestressed anchor cable can increase the normal stress of the sliding band and reduce the sliding force of the sliding body through the prestressing application, effectively enhancing the stability of the landslide body. This paper introduces the construction method of prestressed anchorage cable and the construction process flow. By arranging the construction sequence reasonably, the construction progress is accelerated, the construction quality is ensured, and the optimized utilization of resources is ensured.
