影响边坡稳定性的因素众多,而在实际加固方案设计中,又以锚索间排距、锚索长度、锚固段长度、预应力等4因素影响最大。采用了正交试验的方法,以加固后安全系数作为评价指标,采用4因素3水平,共进行9次试验,对4因素进行敏感度分析,借以确定当这些因素发生变化时,安全系数会怎么变化,变化的幅度如何,由此为边坡的优化设计提供参考。
There are many factors that affect the stability of the slope. However, in the design of the actual reinforcement scheme, the influence of the four factors such as the distance between the cables, the length of the anchor cable, the length of the anchorage section and the prestressing is the greatest. Using orthogonal test method, with the safety factor after reinforcement as the evaluation index, using 4 factors and 3 levels, a total of 9 tests, the sensitivity of the four factors analysis to determine when these factors change, the safety factor will be how Change, change the magnitude of how to optimize the design for the slope to provide a reference.
