地铁运行引起建筑物振动的实测研究与数值分析
Field Measurement Study and Simulation Analysis of Building Vibrations Caused by Subway Operation
摘要
Abstract
In order to study the influence of vibrations caused by subway operation on buildings,field measurements were conducted on the vibration response of a teaching building and the surrounding ground of a university in Guangzhou.The propagation patterns of vibrations were analyzed,and a numerical model was established.After verifying the model's ac-curacy,the influences of different structural characteristics on the propagation patterns of vibration within buildings were studied.The results show that the primary frequency range of ground vibrations is between 30 and 50 Hz.As the distance from the tunnel increases,the overall ground vibrations gradually decrease,but there is a vibration amplification zone at a certain distance from the tunnel.With the elevation of the floors,the vibrations of the columns,beams and slabs all show an overall increasing trend.Enlarging the column cross-section,enlarging the beam cross-section,increasing slab thickness,and increasing the number of floors can all reduce the vibration response of the buildings.Among all the parameters,increasing the number of floors has the most significant effect on the vibration response of the building.These findings may provide a reference for engineering design.关键词
