摘要
预应力锚索被广泛应用于边坡及滑坡工程的加固,并获得了良好的加固效果和经济效益。但预应力的不稳定变化关系到工程运营期的安全性,因而研究锚固工程的设计施工显得非常重要。锚固工程只有采取有效措施把不利因素控制在允许范围内,才能确保工程的安全稳定。本文通过对岩土体加固中采用的预应力锚固体进行分析,详细讨论了影响预应力锚索锚固力的变化因素,得出了不同影响因素对预应力锚固工程中的设计施工问题的危害,总结了目前预应力锚索设计施工中容易出现的问题,并提出了解决办法与对策措施。
Pre-stressing anchor is applied to reinforcing slope and landslides engineering, and has gotten good strengthening effect and economic benefit. The design and construction of pre-stressed anchor will influence the security of the project, and it is very important to study the fluctuating variation of the stress. In order to ensure the safety of the engineer, effective measures must be adopted to control the impact. Based on studying the performance of widely used pre-stressed grouted rock anchors in projects, the factors affecting on the anchoring were discussed, and draw up the problem of design and construction of geo - engineering. The shortcomings of the specifications are pointed out, and the ways to deal with are presented.
