摘要
以横琴市市政工程为例,根据所穿地道的特殊地质条件,在山体基岩与淤泥层施工下穿地道。通过合理组织下穿地道软基处理与结构主体施工总体部署,顺利完成汽车下穿地道施工。介绍了工程的施工难点与施工方法以及不同里程段的基坑支护形式。
Based on the Hengqin municipal engineering, according to the special geological environment of the tunnel, the tunnel was constructed in the bedrock with silt layer. Through reasonable organization of soft soil foundation treatment and overall deployment of main structure construction, the tunnel construction was completed well. Difficulties and construction methods were introduced as well as the foundation excavation supports method in different parts.
