摘要
基于某工程边坡锚索预应力变化的系统监测和资料分析,根据锚索应力衰减的速度将锚索应力的损失分为快速损失阶段、缓慢损失阶段、相对稳定三个阶段,分析了影响各阶段应力损失的主要因素。工程实例表明,锚索应力监测数据能够实时的反映坡体的变形,在边坡的防护和稳定性评价中发挥重要作用。
This paper presents a case history of the monitoring and data analysis of the pre-stressed ground anchors for a slope stability remediation project.The data indicates that the pre-stress loss can be divided into three stages：Fast pre-stress loss,gradual loss and relative stable.The influence factors that affecting the stress loss have been summarized.The project results indicates that the pre-stress monitoring can provide the real time information about the deformation of the slope and the monitoring plays a critical role in the slope stability analysis as well as the mitigation.
