| 摘 要： | 预应力锚索在高速公路边坡危岩治理中,对锚索预应力损失进行了现场试验,在对2根压力分散型锚索进行了6个月锚固力监测后,获得了锚固力随时间的衰减变化规律,结果表明锚固力损失受多次循环张拉影响而偏小。

| Abstract: | Pre-stressed anchorage cables were used in the treatment of slope dangerous rocks of an expressway.During the treatment field tests were carried out on pre-stress losses of the anchorage cables.The results of the 6-month's monitoring and metering of anchorage stress of two anchorage cables with dispersed stresses provided the law of anchorage stress decreasing with time.The results reveal that the anchorage stress loss becomes less than what it should be due to repeated tensioning of the anchorage cable. |
