摘要
武广高速铁路金沙洲隧道是我国首次在复杂地质条件下下穿城市立交桥的浅埋特大断面(大于160m2)隧道。为了确保施工过程安全可控,对沙贝立交枢纽进行风险辨识和风险评估,根据评估结果,在洞内外采取了有效的降低施工风险的处理措施,确保了浅埋特大断面隧道下穿立交枢纽的安全,可供类似工程参考。
Jinshazhou tunnel at Wuhan-Guangzhou High-speed railway is China＇s first shallow tunnel with large section（greater than 160 m2） under complicated geological conditions beneath urban overpass.In order to ensure safe and controlled work in construction process,the risk assessment and the risk identification of the Shabei interchange hub were studied.According to the results of the assessment,effective measures were taken to reduce construction risk in the cave.The security of the interchange hub beneath the shallow tunnel with large section is ensured.This paper could be as a reference to the similar projects.
