随着城市建设的不断推进,地铁沿线区域的土地利用率不断上升,邻近地铁的超大、超深基坑开挖工程中的基坑变形控制等问题日益显现。结合顶新国际集团(上海)商务中心工程施工实例,在邻近地铁的深基坑施工过程中应用时空效应原理,采取对土方开挖分区面积的控制、土方开挖进度的动态调控和运用支撑轴力自动补偿等方式,控制了基坑变形和邻近地铁区间的土地变形。 With the continuous development of urban construction, the land utilization rate in the area along the MTRC is on the rise. The problems such as deformation control of foundation pits in excavation of very large and ultra-deep excavation near the subway are increasingly apparent. In combination with the construction project of Dingxin International Group (Shanghai) Business Center, the principle of space-time effect is applied in the construction process of deep foundation pit near the subway. The control of the excavation area of ​​earthwork, the dynamic regulation and control of earthwork excavation progress, Force automatic compensation, etc., to control the deformation of the foundation pit and the land near the subway deformation.
