摘　　要：近年来,随着城市建设的发展,城市路面塌陷已经成为各城市地质灾害的主要类型之一,日益引起人们的关注。城市路面塌陷一般规模不大且多为单点式塌陷,但一旦发生则成为影响城市生活的突发公共事件。通过对全国各地公开报道的塌陷案例进行总结分析,结果表明:城市路面塌陷一般可分为岩溶型、管道型、工程施工质量型、防空洞型等四种;城市路面塌陷与城市发展程度密切相关,与岩溶发育程度的相关性反而不明显;暴雨是路面塌陷的主要诱发因素之一;路面塌陷以单点式塌陷为主,规模不一。进一步地,从前期塌陷隐患识别、中期应急预案、后期工程处置角度出发,对四种城市路面塌陷分别提出了相应的处置方案,为今后城市路面塌陷相关研究以及塌陷预防、应急、处置方案提供参考。In recent years,with the development of urban construction,the collapse of urban pavement has become one of the main types of urban geological disasters,which attracts people s attention increasingly.Urban pavement collapse is generally small in scale and mostly single point collapse,but once it occurs,it will become an emergency affecting urban life.This paper summarizes and analyzes the collapse cases publicly reported throughout the country,and the results show that urban pavement collapse can be generally divided into four types:karst type,pipeline type,construction quality type and air-raid shelter type.The subsidence of urban pavement is closely related to the degree of urban development,but the correlation with the degree of karst development is not obvious.Rainstorm is one of the main inducing factors of pavement collapse.Pavement collapse is mainly single point collapse with different scales.Further,from the perspective of early collapse hidden danger identification,mid-term emergency plan and late project treatment,the corresponding disposal schemes for the four types of urban pavement collapse are respectively proposed,providing reference for future urban pavement collapse related research and collapse prevention,emergency and disposal schemes.
