摘要
目前,公路工程地质评价尚不成熟,无法定量地对工程地质条件的适宜性做出评价。本文应用区间数模糊层次分析法构建了工程地质评价模型,形成了一套完整的工程地质评价方法,将区间数理论和数模糊层次分析法结合,极大提高了数据的利用率,使评价结果更精确。以孔隙度为例,示范了指标层隶属度区间的确定方法,并求得5个岩石样品模糊集合为A=(0.1,0.05,0.25,0.2,0.2),隶属度区间为[0.05,0.2]。
At present,the highway engineering geological evaluation is not mature,and it is unable to evaluate the suitability of engineering geological conditions quantitatively.In this paper,the interval number fuzzy analytic hierarchy process is used to build the engineering geological evaluation model,forming a complete set of engineering geological evaluation methods.The combination of interval number theory and fuzzy analytic hierarchy process can improve the utilization rate of test data and make the evaluation results more accurate.Taking porosity as an example,the determination method of membership interval of index layer is demonstrated,and the fuzzy sets of five rock samples are obtained as A=(0.1,0.05,0.25,0.2,0.2),and the membership degree interval is[0.05,0.2].
