地裂缝场地地铁运行引起框架结构振动的数值分析
Numerical Analysis for Frame Structure Vibration Induced by Metro Operation in Ground Fissure Area
摘要
Abstract
Focusing on the vibration problem of buildings induced by Xi’an metro operation in ground fissure area, a three-dimensional finite element model including tunnel, ground-fissure and frame-structure is established. Model analysis and vibration response analysis of the buildings are conducted. The results are compared with those of the same model under the same loading condition but the ground fissure effect is not considered. It is indicated that the structure’s vertical vibration is stronger than the horizontal one; the ground fissure has little effect on the distributions of horizontal and veridical vibration accelerations. The former shows a fluctuating distribution with the floor rising, while the latter only shows insignificant difference of all the floors except the first floor. The ground fissure has large influence on the distribution of the vertical acceleration. It increases with the floor rising in the non-ground fissure area, while in ground fissure area, it decreases initially and increases later with the floor rising. The ground fissure causes the increasing of frame’s vertical vibration acceleration, both vertical and horizontal vibration acceleration increases in some floors.关键词
