深圳滨海大道西行沙河立交附近8月4日9时许发生地面沉降，未造成人员伤亡[1]。事发后实施交通管制，引发福田往南山方向多条道路长距离拥堵[1]。截至报道发稿，沉降具体原因、抢修进展及主道恢复时间均未公布[1]。
8月5日12时30分，该路段辅道解封恢复通车[1]，但主道仍然封闭抢修[1]。晚高峰时段，路段再次出现大面积拥堵，车辆通行缓慢[2]。
对于此次事件，四川省地质局教授级高级工程师范晓指出，处置不能只于回填路面，应查明地下致因[1]。深圳市人大代表陈雄英表示，事件暴露了地质风险防范、路网结构和突发事件信息发布等多方面短板[1]。根据深圳市规划和自然资源局数据，2017至2023年间，给排水管道破损、施工不当、路基回填不密实是地面沉降的主要原因，合计占比超过90%[1]。同一路段曾在2024年10月12日发生过地面塌陷，塌陷面积约50平方米、深度约2米[1]。
A significant ground subsidence occurred along the westbound section of Shenzhen's Binhai Avenue near the Shahe Interchange at approximately 9 a.m. on August 4, 2024, with no casualties reported [1]. The incident prompted immediate traffic controls, triggering extensive congestion across multiple routes from Futian to Nanshan districts [1]. By August 5 at 12:30 p.m., auxiliary lanes were reopened to traffic, though the main carriageway remained closed for emergency repairs [1].
As of the initial reporting, authorities had not disclosed the precise cause of the subsidence, specific repair progress, or an estimated timeline for full restoration of the main road [1]. This lack of transparency raised broader concerns about geological risk management, road network design, and emergency communication protocols. A geology professor-level senior engineer from Sichuan Geological Bureau, Fan Xiaohui, emphasized that remediation must extend beyond simply refilling the damaged surface, stressing the importance of investigating underlying geological causes [1]. Meanwhile, Shenzhen People's Congress representative Chen Xiongying highlighted that the incident exposed multiple vulnerabilities, including inadequate geological hazard prevention, structural limitations in the road network, and deficiencies in public emergency information disclosure [1].
Historical data from Shenzhen's Planning and Natural Resources Bureau indicates that between 2017 and 2023, the primary causes of such incidents were water and sewage pipe damage, improper construction practices, and inadequately compacted road base fill, collectively accounting for over 90 percent of cases [1]. The same stretch of Binhai Avenue had experienced a ground collapse incident on October 12, 2024—involving a subsidence area of approximately 50 square meters and a depth of about 2 meters [1]. On the evening of August 5, repair crews continued work on the affected segment, with auxiliary roads restored but peak-hour congestion persisting across the corridor [2].
