Multi-objective Optimization Model of Foundation Pit Dewatering Based on Paretosearch Method
摘要
Abstract
In order to optimize the dewatering scheme of foundation pit,the foundation pit dewatering project of permeable stratum in the inverted siphon section of Xixiayuan canal head is taken as the research object.Firstly,through the design of pattern search algorithm,the multi-objective optimization model,and the Paretosearch program based on the pattern search method in MATLAB optimization toolbox,an iterative program for multi-objective optimization of foundation pit dewatering is developed to solve the Pareto solution set,and the solution flow is given to solve the multi-objective optimization mathematical model.Secondly,the multi-objective optimal evaluation system of dewatering is established by using analytic hierarchy process(AHP),and the Pareto optimal solution set is selected as the basis of decision-making optimization from three aspects of the dewatering cost,the impact of land settlement on environment and the safety and stability of foundation pit.Finally,the GMS software is used to verify and analyze the optimization scheme.The results show that the optimized scheme meets the requirements of water level and settlement control,and the optimized program can solve the multi-objective optimization problem of foundation pit dewatering efficiently.关键词
