摘要
在已运行地铁线路沿线新建、改建和扩建工程项目,特别是基坑面积较大且开挖深度较深的项目,如何控制土体变形,避免对地铁的正常运营产生影响,是施工中的重点和难点。以杭州港龙城地铁上盖项目为例,为控制地铁隧道的变形,在深基坑施工中采取了相对应的技术措施,收到了较好的效果,可为同地区类似工程提供借鉴。
In the newly constructed, reconstructed and expanded projects along the existing metro lines, especially those with large foundation pit and deep excavation depth, the question of how to control soil deformation to avoid its effect on the normal operation of metro is the key and difficult point in construction. Taking superstructure project of Hangzhou Ganglongcheng subway as an example, in order to control the deformation of subway tunnel, the corresponding technical measures have been taken in the construction of deep foundation pit, which has received favorable effect, and can provide references for similar projects in the same region.
