浅议水利水电工程建设浅谈岩溶区公路路基稳定性的区间模糊评判分析

Abstract There are many methods for studying the highway roadbed stability in karst area. In this paper combined with the featuresof the roadbed stability the interval fuzzy evaluation method is used to do comprehensive analysis of the highway roadbed in karst area. Byjudging the relative membership degree and weight vector method the suitable method for the development of the highway roadbed stabilityin karst area is worked out and the final test results and using method are found out. This method makes the karst area highway roadbedstability evaluation more reasonable and operational.院路基稳定的相对优势度 非线性模糊矩阵合成算子 模糊评判 区间分析Key words the comparative advantage index of the stability of the roadbed nonlinear fuzzy matrix synthesis operator fuzzy evaluation interval analysis中图分类号院U416.1 文献标识码院A 文章编号院1006-4311（2014）06-0072-020 引言岩溶区公路路基稳定性评价是岩溶地区公路建设的关键技术问题之一。目前，岩溶区公路路基稳定性评价方法分为半定量经验与非确定性分析方法两大类。半定量经验性分析方法主要有基于极限平衡理论 坍塌堵塞概念与破裂拱概念给出的岩溶顶板临界厚度估算方法 盖层土体-薄顶板溶洞力学分析方法 三维有限元法等。非确定性分析方法最具代表性是模糊综合评判方法，它较合
