确定预应力锚索设计参数的优化方法

在水利水电工程建设中 ,通常采用预应力锚索 (杆 )加固不稳定边坡以改善其稳定性。然而 ,至今为止 ,对预应力锚固的设计大多过于保守 ,造成过多的工程浪费 ,锚固设计理论与方法有待于深入研究。通过对影响岩锚设计参数的因素分析 ,应用优化与决策理论 ,提出了岩锚设计参数的确定方法 ,建立了岩锚支护设计决策支持系统 RSASYS,为工程设计人员进行岩锚设计提供了一种新的分析方法。实践证明该方法可行并可获得巨大的经济效益。

Optimization for Determination of Parameters for Prestressed Cable Design

In hydroelectric project construction, usually, the stability of unstable slope is improved by prestressed cable (bolt). However, up to now, the design of prestresed anchor was rather conservative, leading to over consumpion in engineering. So there is a need to have more study on theory and method of anchor design. Based on analysis of factors influencing the design parameters with application of theory of optimization and decision, a method for determination of parameters for rock bolt design is suggested. A decision supporting system RSASYS for rock bolt support design has been set up, which can provide a new method for rock bolt design. The practice shows that this method is feasible and gives great economical benefits.
