8月4日上午9时许，深圳滨海大道西行沙河立交附近发生路面塌陷沉降，形成约10平方米以上的路面空洞[1]。事发后相关部门立即进行隔离警戒和应急处置，滨海大道西行5条主路车道全面实施交通管制，晚高峰时段拥堵长龙超过5公里[1]。此次事件未造成人员伤亡和财产损失[1]。
施工人员连夜进行注浆回填作业，截至发稿时路段仍未复通[1]。这是滨海大道两年内第二次发生重大塌陷事件，此前2024年10月12日海韵公园附近曾发生约50平方米、深度达2米的塌陷[1]。
A section of Shenzhen's Binhai Avenue experienced sudden subsidence on the morning of August 4, 2024, creating a surface cavity exceeding 10 square meters near the Shahe interchange on the westbound carriageway [1]. The incident prompted immediate emergency response, with authorities establishing cordons and implementing multi-lane traffic controls [1]. The disruption during evening rush hour resulted in traffic congestion stretching beyond 5 kilometers [1].
Following the discovery, construction crews initiated grouting and backfill operations that continued through the night [1]. As of the time of reporting, the affected section remained closed to traffic [1]. No casualties or property damage were reported [1]. This incident marks the second major subsidence event on Binhai Avenue within two years, following a previous collapse of approximately 50 square meters with a depth of 2 meters near Haiyun Park [1].
