| 摘 要： | 通过试验发现锚索框架梁的受力分析必须分为张拉阶段和工作阶段,但工作阶段不是从锚索锁定后算起,而是从边坡有下滑的趋势算起比较合理;同时还进一步探讨了12节点预应力锚索框架梁的内力和作用于框架梁上土压力的分布,获得了框架梁内力及土压力的分布型式,并通过对预应力锚索的长期观测,得出了软岩高边坡锚索预应力的损失情况及一般规律,这将为同类高边坡工程的稳定性分析及其处理提供重要参考。

| Abstract: | This paper discussed the distributions of the internal forces and the pressures with 12 nodes frame beam through the monitoring test and obtained the distributing patterns.Meanwhile,the author analyzed the pre-stressed loss situation of the anchor-ropes in high rocky slope based on long-term observating data,and obtained the general rule of pre-stressed loss of anchor-ropes. |
