摘　　要：随着城市快速发展,大量河道被覆盖形成暗渠,对地面安全构成严重威胁。采用资料收集和现场调查相结合的方法,对深圳市河道暗渠现状、上盖物业设施和存在的安全隐患进行分析。同时以典型暗渠化河道笔架山河为例,分析河道暗渠段的主要结构性缺陷及整治必要性。结果表明,深圳市暗渠化河道192条,占河道总数量的50.59%。在暗渠结构上,钢筋混凝土箱涵结构的暗渠最长,占比为77.78%,且安全隐患数量比例达到74.02%。在研究暗渠安全隐患的基础上,针对不同等级结构性缺陷提出了防治对策,并建议结合城市更新、暗渠复明等工程进行综合整治。With the rapid development of cities,a large number of river channels were covered to form underdrains,which posed a serious threat to the surface security.Combined with data collection and field investigation,the current situation of underdrains,the property facilities and the existing safety hazard in Shenzhen were analyzed.At the same time,taking the Bijiashan River underdrain as an example,the main structural defects of the channel underdrain section and the necessity of regulation were analyzed.The results showed that there were 192 underdrains in Shenzhen,accounting for 50.59%of the total number of channels.Concerning the underdrain structure,the reinforced concrete box structure was the longest,accounting for 77.78%,as well as the number of safety hazards,accounting for 74.02%.On the basis of studying the safety hazard of the underdrain,different preventing and controlling countermeasures are put forward with different grade structural defects.At the same time,it is suggested that comprehensive improvement should be carried out in combination with urban renewal and the restoration of underdrain.
