Assessment of Karst Development Intensity Based on FAHP and Entropy Weight Method
This paper takes the karst phenomenon of Jurong Pumped Storage Power Station as the re-search object,and assesses the intensity of its karst development with comprehensive qualitative and quantitative methods.Starting from the conditions of stratum lithology,carbonate rock burial,geological structure,groundwater,topography,and adverse geological phenomena,17 evaluation indexes affecting karst development such as lithology,rock structure,and rock production ar selected to establish an index system suitable for evaluating the intensity of karst development.The feasibility of the comprehensive ap-plication of the fuzzy analytic hierarchy process(FAHP)and entropy weight method to determine the weights of the influence of each factor on the development of karst is discussed.The evaluation results show that the strength of groundwater flow has the greatest influence,followed by faults and lithological conditons.The weighted values are linearly weighted to get the comprehensive attribute measurements,and the karst development intensity of the three karst hydrogeological units is finally judged.The evalua-tion results are compared with the actual results to verify the reliability of the evaluation model.
