Abstract

The present invention provides a safety evaluation method of slag dump based on fuzzy comprehensive analytic hierarchy process, which comprises the following steps: step A, investigating and summarizing main influencing factors of safety of slag dump, and establishing a hierarchical structure model; step B, respectively establishing a factor set and a weight set according to that hierarchical structure model, and adopting a 9-scale method to calculate the weight of the factor evaluation index; step C, establishing an evaluation grade set according to the practical experience of soil and waterconservation design and construction; step D, determining a membership function and a fuzzy evaluation matrix of each influence factor evaluation index; step E, comprehensively evaluating the safety of the slag dump according to the result of the analytic hierarchy process and the evaluation grade set. The present invention is based on fuzzy theory and chromatographic analysis theory, combined with design and construction practice experience, and combines qualitative and quantitative evaluation to evaluate the safety of slag dumping site. The evaluation result is reasonable and reliable, and has certain innovation. The present invention is simple in operation and easy to be applied in practice, and provides a new method and idea for safety evaluation of slag dumping site.

Description

technical field [0001] The invention relates to the field of safety assessment of spoil grounds in the water and soil conservation industry, in particular to a safety assessment method for spoil grounds based on fuzzy comprehensive hierarchical analysis. Background technique [0002] In recent years, there have been frequent occurrences of destabilization accidents at spoil dumps, such as the 6.28 debris flow incident in the construction area of ​​Baihetan Hydropower Station, the Shenzhen 1220 landslide incident, and the "8.1" super dump dump accident at Loufan Jianshan Iron Mine in Shanxi Province. The safety of people's life and property poses a great threat. Due to the influence of engineering design and construction, there are many problems in the spoil site, such as the inconsistency between the design plan and the construction site, potential safety hazards in the spoil site, littering during construction, imperfect protection measures, and poor construction quality of...
