摘要
通过对新建地铁隧道下穿既有车站的情况进行分析,得出了下穿隧道对上部既有车站的影响规律。采用FLAC3D 4.0有限差分软件进行三维数值模拟,对CRD法施工对既有上部既有车站造成的沉降进行研究,得出了既有车站的沉降量最大值以及沉降速率最大值的位置。对工程的施工具有指导意义。
Analyzing the new subway tunnel through existing station,get the rule that new subway tunnel affects upper existing station. FLAC3 D 4 finite difference software is used for 3D numerical simulation,The settlement caused by CRD method for existing upper station is studied. The maximum settlement value and the maximum settlement rate of the existing station are obtained. This conclusion has guiding significance to engineering construction.
