| 摘 要： | 结合广州地铁5号线盾构施工中遇到的过街通道桩基础处理问题,对处理方案进行了分析比较,提出了合理的人工挖孔桩+钢纤维喷射混凝土横通道方案,通过自下而上分层施工,实现了在软土地层中横通道无筋支护施工,解决了盾构通过范围不能遗留钢筋混凝土的难题,并控制了风险.该方案在施工中得到了成功应用,对于其他类似工程,具有良好的实践参考价值.

| Abstract: | Some issues aroused in the construction of Guangzhou Metro Line No.5 have been analyzed.The pile foundation of underground free way is analyzed emphaticaly.The reasonable scheme combined the man-made hole-pole & the passage of steel fiber shotcrete is proposed through layered construction from bottom to top;the transverse passage in soften stratum can be constructed without reinforcing steel bar;thus it will help clearing away the stumbling blocks for the future shield tunneling and controlling the risks during the construction.This scheme has been applied to construction and approved of a practical and instructive way to other similar projects. |
