摘要
以三明学院新建工科实训大楼土质挖方边坡锚索预应力监测和分析为例,在阐述监测方法的基础上,根据锚索预应力变化数据将锚索预应力损失分为锁定时损失、快速损失、随机摆动损失、相对稳定4个阶段,结合理论公式对各阶段实际预应力损失进行定量分析。分析结果揭示了该类型边坡锚索预应力的变化规律,对同类工程具有一定的指导意义。
This paper takes the prestress monitoring and analysis of the soil excavation slope of the newly built engineering training building of Sanming College as an example.Based on the monitoring method, the anchor cable prestress loss is divided into four stages, i.e.locking loss, rapid loss, random oscillating loss and relative stability according to dynamic data of the anchor cable prestress.Combining with the the oretical formula, the paper calculates the quantitative analysis of the actual prestress loss at each stage.The results reveal the law of stress variation of this type of slope anchor cable, which has certain guiding significance for similar projects.
