摘要
根据模型试验研究结果，给出了模拟软岩材料的蠕变方程，探讨了锚索张拉吨位随时间的变化特征，分析了张拉吨位损失后的稳定值与初始张力之间的关系。在此基础上，提出了锚索张拉吨位随时间而损失的估算方法。
The creep equation of simulated material of soft rocks is given through model testing research on soft rocks reinforced by prestressed anchor cable. The characteristics of prestress of anchor cable varied with time are discussed in particular. Then the relationship between the initial prestress and the stable prestress in anchor cable is analyzed. Based on above results, an estimating method of pulling force of anchor cable decreased with time is finally proposed.
