摘　　要：近些年来,极端暴雨天气频发,同时城市下垫面雨水吸收能力下降,使得城市雨水管网系统面临着更大的挑战。为了对暴雨天气下城市雨水管网系统的韧性进行量化,通过将PSR模型相结合与韧性理论,建立适于暴雨天气下城市雨水管网系统韧性评估指标体系,选取G1法与COWA算子分别确定指标权重,通过博弈论的思想进行权重组合,并与云模型评估模型相结合,构建组合赋权—云模型的韧性评估模型,以贵州省D市整体开发程度较高的某片区域雨水管网系统为例,进行模型验证。结果表明:该研究区的城市雨水管网系统韧性等级属于一般韧性等级,该模型具有一定的科学性与可行性。In recent years,the extreme rainstorm weather occurs frequently,and the rainwater absorption capacity of urban underlying surface decreases,which make the urban rainwater pipeline network system face the great challenges.In order to quantitatively study the resilience of urban rainwater pipeline network system under heavy rainfall conditions,a toughness evaluation index system suitable for urban rainwater pipeline network system under rainstorm weather is established by combining the PSR model with the toughness theory.The G1 method and COWA operator are used to determine the indices weights respectively.Through the thought of game theory,the weight combination is carried out.And combined with the cloud evaluation model,the resilience assessment model of composite empowerment-cloud model is established.Taking the rainwater pipeline network system in an area with higher overall development level in D City of Guizhou Province as an example,the model is verified.The results show that the resilience level of the urban rainwater pipeline network system in this studied area belongs to the general resilience level.This model has a certain level of scientificity and feasibility.
