立体交叉
In this paper, it is mainly discussed that changes of the vehicle weight and vehicle speed affect the vertical displacements, vertical accelerations and horizontal stresses of the grade crossing plate.
着重讨论车辆轴重、速度的改变对道口板的竖向位移、竖向加速度和水平应力的影响。
Result showed: During the lower tunnel crossing construction when upper tunnel was normal operating, because of the subway train vibration, the tunnel under construction and in-built both had large vertical vibration responding displacement increment.
结果表明:当上部隧道正常运行状态下进行隧道下行穿越施工时,由于地铁列车振动荷载作用下穿隧道及运营地铁隧道都将产生较大的竖向振动响应位移增量。
