基于改进模糊层次分析法的病险水库除险加固效果评价OA

In order to select a feasible reinforcement scheme and improve the working performance of hazardous reservoirs to the greatest extent,a multi-level optimization model of reservoir reinforcement scheme was constructed based on the comprehensive consideration of the implementation effect,reasonable cost,technical feasibility and convenient construction of the reinforcement scheme. The improved fuzzy analytic hierarchy process of accelerated genetic algorithm was used to determine the weight of each optimization subsystem and index. A multi-level optimization evaluation method for reservoir reinforcement effect was proposed,and a typical reservoir was selected for verification.The results showed that for the preferred subsystem,the weights of the technical feasibility subsystem and the effect reliability subsystem were larger,which were 0.309 and 0.298,respectively. For the preferred index,the comprehensive weight was the level of the construction unit,the degree of satisfaction of the stability requirements,the adaptability of the reinforcement scheme to the cause of the reinforcement of the induce dam,the reinforcement scheme and the regional adaptability of the dam. The comprehensive evaluation value(0.797)of plastic concrete cut-off wall scheme in typical reservoir application examples was relatively better.
