受连日降雨影响，深圳滨海大道西行方向沙河立交附近于8月4日出现地面沉降并进一步发展为局部塌陷[1]。塌陷面积约为20平方米[1]，该路段处于填海区地质条件复杂[1]。相关部门随即启动应急预案进行处置，并于8月5日8时完成回填加固[1]。
道路恢复通行工作分阶段进行[1]。8月5日中午，滨海大道深湾五路至沙河东立交段西行辅道3车道恢复通行[1]。8月6日14时20分，西行主车道左侧2车道恢复通行，右侧3车道因施工仍需封闭约300米[1]。
A section of Shenzhen's Binhai Avenue experienced ground subsidence that developed into a localized collapse on August 4 due to sustained rainfall, according to an official report[1]. The affected area, located near the Shahe interchange on the westbound carriageway, covered approximately 20 square meters[1]. The collapse occurred in a reclaimed land zone where geological conditions are inherently complex[1].
Emergency response procedures were activated immediately to address the incident[1]. Backfilling and reinforcement work was completed by 8:00 a.m. on August 5[1]. Traffic recovery proceeded in phases: by midday on August 5, the westbound auxiliary lanes between Shenzhen Bay Fifth Road and the Shahe East interchange had resumed normal operations[1]. The following day at 2:20 p.m. on August 6, the left two lanes of the westbound main carriageway were reopened, while the right three lanes remained closed for construction over a distance of approximately 300 meters[1].
