不同基础隔振装置对地铁周围建筑物振动影响研究
Research on the Influence of Different Base Isolation Devices on the Vibration of Buildings Surrounding the Subway
摘要
Abstract
To investigate the impact of different base isolation devices on the vibration and noise of buildings surrounding the subway,rubber bearings and disc spring vibration isola-tion supports were selected.A vehicle-track coupling model was established using the multi-body dynamics software UM.This model facilitated the simulation and calculation of the vertical wheel-rail force when the subway train was operating at a speed of 80 km/h.A tunnel-soil-building model was constructed in the finite element software ABAQUS.The wheel-rail force was applied as an external load,and a simulation analysis was conduc-ted to research the effects of vibration isolation elements on subway vibration and noise.The research results show that rubber bearings and disc spring vibration isolation bearing can effectively reduce the vibration acceleration of each floor of the building.Compared with no vibration isolation,the peak values of vertical vibration acceleration at the center of the fifth floor of the building with isolation devices are reduced by 41.31%and 59.64%,respectively.Additionally,the Z-vibration levels are reduced by 4.63 dB and 7.88 dB,respectively.关键词
