边坡锚索预应力监控及其稳定性分析

Monitoring of Side Slope's Anchor-cable Prestress and Analysis for Its Long-term Stability

通过对某高边坡锚索预应力的监控,从锚索预应力损失的快速衰减阶段、缓慢损失阶段以及相对稳定阶段进行探讨,分析影响锚索各个阶段预应力损失的主要因素。在此基础上,建立边坡安全系数随时间变化的函数关系,以预测边坡稳定性,可为实际工程提供参考数据,具有重要的理论意义和工程价值。

Based on the monitoring of a high slope＇ s anchor cable prestress, the rapid decay stage, slow loss stage and stable stage of the anchor cable prestress are discussed here, and then the main causes of each stage are analyzed. On this basis, the safety factor as a function of time is built to predict the long-term stability of slope. By doing this, the reliable reference data could be provided for actual projects, which would have important theoretical significance and engineering significance.
