摘要
Abstract
At present,the renewal and reconstruction of old neighborhoods is vigorously promoted in China.Flooding problems are frequent due to the aging pipe network and outdated design commonly found in old neighborhoods.An old neighborhood containing villas and high-rise apartments in Shanghai is taken as an example,the current situation and the problems are described and a storm water management model(SWMM)of the study area is constructed to as-sess the current status and the drainage condition after the traditional forced-drainage renovation.Leveraging the NSGA-2 algorithm,five Pareto optimal solutions under a 5-year rainfall recurrence scenario are generated,fol-lowed by comprehensive evaluation using an enhanced TOPSIS method.Key findings reveal that traditional pump drainage exhibits limited effectiveness with increasing recurrence periods,necessitating integrated application of LID facilities and intelligent algorithms;Pareto front analysis demonstrates a nonlinear positive correlation between overflow reduction rates and life-cycle costs/land area.When the overflow reduction rate is 75％,the increase of the cost and landare significant;Five representative schemes are identified through extremum screening method and crowding distance principles,among which Scheme 5(life-cycle cost of 22.88 million yuan,land area of 39 766 m2,overflow reduction rate of 77.01％)demonstrates the optimal comprehensive benefits.This research provides a sys-tematic solution for optimizing low impact development(LID)facility layouts of old communities in Shanghai,with valuable references and promotion potential.关键词
