Abstract:
The selection of hazardous waste disposal site is a complicated system engineering problem, and its influencing factors have the characteristics such as information incompleteness, uncertainty, and fuzziness. In this paper, a multi-level and multi-objective evaluation index system was developed in Chengdu City in consideration of geological structure, geographical factors, stratigraphic lithology, hydrogeological conditions, surface drainage, and geological disaster distribution. The fuzzy mathematical comprehensive evaluation method was used to analyze the selection of hazardous waste disposal site in Chengdu City. The results suggested that the fuzzy mathematical improved model is scientific and practical, easy to operate, and has certain practical application value, thus it can provide reference for related projects.
