摘要
深圳地铁科华区间隧道地质条件复杂多变,属浅埋隧道,采用暗挖法施工,施工难度极大。结合施工实际,介绍了该隧道采取的竖井旋喷桩止水帷幕技术、富水软弱地层以及富水砂层的开挖支护技术,分别列举了隧道穿越地下管线、人行天桥、高楼地下室施工时采取的施工措施,总结了控制地表变形沉降的主要对策。
In the Ke-Hua zone of Shenzhen subway tunnel, the geological condition is complicated, the difficulty of construction is high, subsurface-excavated technique is used. Using the actual project as an example, this paper describes some technologies used in tunnel excavation include vertical shaft rotating sprayed pile water stop purdah technology, and the support technology in water-rich weak surrounding rock and water-rich sandstone. Specialize construction measures are used to get through ground cable, over-bridge and basement .Summarize major countermeasures to control surface settlement.
