边坡治理多层次多目标优化决策方法研究

Multihierarchy & Multiobjective Optimization Decision Methods of Slope Treatment Schemes and Its Application

针对边坡治理方案决策是一个多层次多目标的综合评判问题 ,利用最优传递矩阵对常规的层次分析法进行改进 ,建立了边坡治理多层次多目标优化决策的改进的层次分析法 ,该方法求得的判断矩阵自然满足一致性要求 ,不需要进行一致性检验。并以板岩山危岩滑坡治理为实例 ,建立了板岩山危岩滑坡治理决策的层次结构模型 ,对板岩山危岩滑坡治理方案进行了优化决策 。

The decision of treatment schemes of slopes is the comprehensive judgement with multi-objective and multi-hierarchy. The traditional Analytic Hierarchy Process(AHP) needs the identity test. In this paper, the traditional AHP is improved by means of optimal transfer matrix, and the improved AHP of treatment decision schemes of slopes is set up. The judgement matrix obtained by the method can naturally meet the requirement of identity, so the identity test is not needed. The method is applied to the treatment of dangerous rock masses at the Slate Mountain, the hierarchy model of the judgement system of treatment schemes of dangerous rock masses at the Slate Mountain is established, and its analytic result provides scientific decision basis for the treatment of dangerous masses.
