摘　　要：为了使巷道支护参数的决策符合安全经济的目标,通过设计正交实验结合回归分析得出巷道锚喷支护决策指标与支护参数的关系,利用多属性效用理论,将支护参数与决策者对风险的排斥度结合起来,建立锚喷支护的综合效用函数模型,利用MATLAB软件将该模型编程,使用该模型可以方便地求出巷道支护参数的最优方案以及进行多种支护参数的优选。通过实例分析表明,采用该方法对锚喷支护的支护参数设计及优化具有一定的指导意义。现场采用模型求解得出的最优支护参数,巷道发生冒顶片帮现象的次数显著减少,支护效果明显提高。In order to make the decision of roadway supporting parameters conform the goal of safety and economy, the relationship between decision indicators and supporting parameters of roadway anchor-plate retaining was obtained by orthogonal experimental design and regression analysis. Based on the multi-attribute utility theory, the comprehensive utility function model of anchor-plate retaining was established by combining the support parameters with the decision maker's risk rejection degree. The model was programmed by Matlab software. The model can be used to conveniently find out the optimal scheme of roadway support parameters and to optimize a variety of support parameters. The analysis of an example shows that this method has certain guiding significance for the design and optimization of supporting parameters of anchor-plate retaining. The optimized supporting parameters from the model solution are adopted on the site, the number of roof falling accident occurring in the roadway is significantly reduced, and the supporting effect of the roadway is obviously improved.
