摘要
通过对某高速公路滑坡的预应力锚索轴力现场监测,分析了锚索预应力变化规律,预应力锚索轴力可分成三个阶段,分别为速损阶段、稳步下降阶段、基本稳定阶段。同时结合坡体坡面位移监测资料,分析得出在预应力锚索加固后,坡体变形逐渐趋缓。现场监测资料分析表明滑坡在经过加固处理后,整体已趋于稳定。
Based on the monitoring axial force of the pre-stressed cable on the highway landslide, the prestress change rule in cable is studied. The prestress loss can be divided into three phrase： speedy decline phrase, slow decline phrase and relatively stable phrase. In combination with the monitoring re- suits of displacements which are observed on slope surface, it is obtained that after reinforced, the dis- placement of slope can be reduced and will be stable. On-site monitoring results show that the whole landslide after reinforced is in stable condition.
