杭州某工程矩形顶管下穿高速公路沉降规律分析

Analysis on Settlement Law of a Rectangular Pipe Jacking Underpass Expressway in Hangzhou

杭州某工程矩形顶管穿越高速公路节点,为矩形顶管施工技术在杭州砂性土地层中的首次应用。文章通过对顶管穿越过程中的监测数据进行分析,得到了矩形顶管施工过程中地面沉降随顶管进尺的变化规律及地面沉降槽的分布规律,可为类似工程提供参考。

The rectangular pipe jacking of a project in Hangzhou crosses the expressway node, which is the first application of rectangular pipe jacking construction technology in sandy soil layer in Hangzhou. Based on the analysis of monitoring data in the process of pipe jacking crossing, the variation law of ground settlement with pipe jacking footage and the distribution law of ground settlement tank in the process of rectangular pipe jacking construction are obtained, which can provide references for similar projects.
