采用MADIS GTS建立某段区间隧道、岩土、上部建筑整体有限元模型,模拟地铁列车以40km/h速度从建筑物下部穿过时,隧道、岩土、上部结构的振动响应,对上部建筑物产生的振动加速度级与我国《城市区域环境振动标准》中振级的标准限值进行对比,结果表明下部列车运行对上部建筑产生的振动加速度级超出了标准限值要求,最后给出了一些减少上部建筑物振动的建议,以减少地铁列车运行产生的振动对建筑物内人们生活的影响。
The MADIS GTS is used to establish a certain finite element model of the tunnel, geotechnical and superstructure in the interval to simulate the vibration responses of the tunnel, soil and superstructure when the subway train passes through the lower part of the building at the speed of 40km / h, Compared with the standard limits of the vibration level in “Urban Regional Environmental Vibration Standard”, the results show that the vibration acceleration level of the upper part of the train running beyond the standard limit exceeds the standard limit, and finally some measures to reduce the upper part Building vibration recommendations to reduce the impact of subway train operation on the lives of people in the building caused by the vibration.
