[目的]对城市排水系统进行韧性评估，可以了解系统的性能水平，为系统优化提供基础和依据，从而更好的利用地区现有设施的排水能力。[方法]在梳理城市排水系统韧性概念、发展和应用的基础上，从评估情景、评估指标、评估对象和评估方法四个视角系统总结了城市排水系统韧性评估的研究现状，并提出了目前城市排水系统韧性评估存在的不足之处和未来研究方向。[结果]城市排水系统不仅要应对正常降雨情况，还要适应极端天气条件和未来不可预见的干扰。研究表明，除了气候变化、极端降雨导致水力过载的外部荷载，城市复杂的排水网络面临着越来越多的挑战，如由短期偶发性事件(管道坍塌、堵塞)或者长期慢性压力(管道老化)导致潜在的结构失效，这可能会增加基础设施瘫痪、财产损失和潜在生命损失的风险。[结论]目前城市排水系统韧性评估更多地关注功能和系统本身，而随着气候变化和未来多重不确定威胁，需要对城市排水系统韧性进行更加全面和综合的评估，未来将考虑从构建完整情景、选取多维评价指标和多系统协同融合等方面开展研究。
Research progress on urban drainage system resilience evaluation
[Objective]The performance level of the urban drainage system can be understood through resilience evaluation,which also provides a foundation and justification for system optimization to better utilize the drainage capacity of existing facili-ties.[Methods]Based on the concept,development and application of urban drainage system resilience,the research status of urban drainage system resilience evaluation is systematically summarized from the four perspectives of evaluation scenarios,evalu-ation indexes,evaluation objects and evaluation method,and the deficiencies and future research directions of the current urban drainage system resilience evaluation are proposed.[Results]Urban drainage systems have to cope not only with normal rainfall conditions,but also adapt to extreme weather conditions and unforeseen future disturbances.Studies have shown that in addition to external loads from climate change,extreme rainfall leading to hydraulic overloads,complex urban drainage networks face in-creasing challenges such as potential structural failures due to short-term episodic events(pipe collapses,blockages)or longterm chronic stresses(pipe deterioration),which may increase the risk of infrastructure paralysis,property damage and potential loss of life.[Conclusion]The current urban drainage system resilience evaluation focuses more on the function and the system itself,whereas with climate change and multiple uncertain threats in the future,a more comprehensive and integrated evaluation of the resilience of the urban drainage system is needed,and future research will be considered in terms of constructing complete scenarios,selecting multidimensional evaluation indicators,and synergistic integration of multiple systems.
