| 摘 要： | 四川岷江紫坪铺水利枢纽工程引水发电洞进水口边坡布置了大量预应力锚索进行加固，并安装了13台锚索测力计进行监测。本文在对锚索测力计监测资料整理分析的基础上，重点分析了锚索预应力随时间变化的关系、预应力损失情况及预应力损失的原因，对锚索预应力损失的控制有重要的借鉴意义。

| Abstract: | Vast prestressing anchors are arranged at intake slope located at diversion cave of Zipingpu Hydro-junction Project. These anchors are monitored by thirteen anchor monitors. Based on datum drawn from anchor monitors, the authors studied the prestressing-time curve of anchor cables, and the prestressing loss of anchors and its cause. |
