Abstract:

本文提出了模拟地铁环境振动的浮置板-隧道-地层三维有限元模型,振动源为实际观测的地铁钢轨振动加速度.本文旨在研究拟建的北京地铁16号线对200m远处的北京大学场效应电子显微镜TecnaiF30(以下简称F30)工作可能造成的影响.为此,首先模拟了运营中的北京地铁4号线通过北京大学东门站对F30的影响,然后以与16号线相同车型、相同轨道半径的上海地铁7号线实测钢轨振动加速度作为振动源输入,模拟和预测了16号线地铁对F30工作可能造成的影响.结果表明4号线模拟结果显示在140m观测点无论单线还是双线运行,都有部分频段(3~5Hz)进入F30的非工作区,而16号线在200m远处仅是横向加速度在0~0.8Hz和4~6Hz范围进入非正常工作区,垂向加速度在5~6Hz范围内进入非正常工作区.
