摘　　要：近年来城市极端暴雨内涝事件频发,给地下工程的安全及韧性带来了巨大的挑战。鉴于此,本文提出了一种暴雨内涝条件下城市地下工程韧性评价方法。首先,通过暴雨情景模拟,研究了地下工程进水过程的规律。其次,从人员安全通行率的角度建立了暴雨内涝条件下地下工程性能函数,揭示了不同进水情况下地下工程可通行的性能变化规律,提出了从安全通行角度出发的地下工程韧性指标定量计算方法。最后,通过典型案例进行了方法应用,考虑暴雨重现期和挡水设施等因素,揭示了暴雨内涝条件下典型地下工程韧性的变化规律。研究结果表明:暴雨内涝条件下,地下工程韧性随暴雨强度增加而减小,随挡水设施高度增加而显著增加。Due to the frequent occurrence of extreme rainstorm waterlogging events in recent years,the safety and resilience of underground engineering have been greatly challenged.Therefore,a resilience evaluation method was proposed for urban underground engineering under rainstorm and waterlogging conditions.Firstly,the law of the water intake process in underground engineering was studied through rainstorm scenario simulation.Secondly,the underground engineering performance function under the condition of rainstorms and waterlogging was established from the perspective of personnel safe passage rate,and the passable performance variation rule of underground engineering under different influent conditions was revealed.The quantitative calculation method of underground engineering toughness index from the perspective of safe passage was proposed.Finally,the method was applied through a typical case,and the change law of resilience of typical underground engineering under rainstorm waterlogging conditions was revealed by considering factors such as rainstorm recurrence period and retaining facilities.The results show that the resilience of underground engineering decreases with the increase of rainstorm intensity and increases with the increase of retaining facilities'height.
