山区公路岩堆防治方案优化方法及应用

Study on the Optimization of Treatment Schemes of Talus in Mountain Area Road

岩堆边坡防治往往同时具有多个可供选择的防治方案,其决策分析过程是一个多属性多层次多目标评判问题,为此,提出了一种山区公路岩堆防治方案优化方法,该方法基于最优传递矩阵理论,改进常规的层次分析法,建立岩堆防治方案选择优化的改进层次分析模型,进而对岩堆防治方案进行优化。以宜巴高速公路三里花岩堆边坡防治为实例,详细讨论文中的方法在岩堆边坡防治优化决策中的应用。该研究成果为岩堆边坡防治提供了重要的参考。

Talus slope prevention often has some alternative treatment scheme, and the decision of treatment schemes of slopes is the comprehensive judgment with multi-objective and multi-hierarchy. So this article puts forward a optimiza- tion method for the treatment scheme of talus slope in the mountain area highway, which use the optimal transfer matrix to improve conventionally analytic hierarchy process and make it naturally meet the requirement of identity, so the identi- ty test is not needed. As an example, the method is applied to Sanlihua talus slope prevention at the Yiba highway, and the methods of prevention and control in the optimization of treatment schemes of talus are detailedly discussed.
