基于物元分析与云模型的地下工程围岩稳定性评价
Evaluation of underground engineering surrounding rock stability based on matter-element analysis and cloud model
摘要
Abstract
Aiming at the problem of fuzziness and randomness existing in the process of the rock stability evaluation, five indexes including rock quality designation, uniaxial compressive strengthen,rock mass integrality coefficient,strengthen coefficient of structural plane and seep-age measurement of groundwater were selected to be the underground engineering rock stability evaluation index system.Based on the matter-element analysis method,the significance of evalu-ation indicators was confirmed by calculating the validity matter-element of expert j udgment ma-trix and the synthetic weight matter-element.The comprehensive cloud model of each evaluation factor belonging to each evaluation level had been generated based on the certain evaluation stand-ard.According to the measured data of the second stage proj ect in Guangzhou pump accumulator electricity station,the membership degrees of evaluation factors relative to the evaluation grades were calculated from positive cloud generator,and the comprehensive membership degree was de-termined by combining with the corresponding weight.Finally,the rock stability level was speci-fied by the maximum membership principle.Comparing the evaluation results from the reduced concept lattice fuzzy optimum selection and the RS-TOPSIS method,it can be concluded that the method is accurate and reliable and can overcome the transformational fuzzy randomness between qualitative language and quantitative value,so it can be used to evaluate the rock stability in un-derground engineering.关键词
