| 摘 要： | 目前已提出了多种预应力锚索框架梁的设计计算方法,由于软弱岩体的变形特性,这些方法难以直接应用于软岩高边坡工程,需要加以改进。通过预应力锚索框架梁的施工顺序和实际受力条件的分析,对现行设计计算方法作了一些改进和优化。工程实例表明,这样得出的计算结果与现场测试结果较为一致。

| Abstract: | Some design methods of prestressed anchor rope framework have been put forward.As the deformation character of weak rockmass,these methods need to be improved when applied to high slope in weak rockmass.This paper discussed the construction technique and the forces acting on the framework.To optimize and improve the design methods of prestressed anchor rope framework,a new design method has been put forward in this paper.The results of a high slope are nearly the same from the new method as from the site tests. |
