摘要
中国博览会会展中心综合体(北块)中央广场E区基坑工程施工时,遵循"时空效应"原理进行设计和施工,取得了良好的变形控制效果。结合跨越既有轨道交通车站及区间隧道的基坑工程实例,模拟分析了基坑开挖施工的全过程对既有结构物的变形影响,以指导施工工序,有效地达到了控制变形的目的。
The design and construction of foundation pit of E zone of central plaza of China Fair Exhibition Center Complex(North Block) followed the 'Time-Space Effect' principle, and achieved good deformation control. Combined with the engineering case of foundation pit across existing rail transit station and interval tunnel, the deformation influence of foundation excavation on the existing structure was simulated to guide the construction process so as to effectively reach the deformation control target.
