软土地铁车站结构形式对抗震性能影响的研究
Study on Aseismatic Ability of Subway Station on Soft Soil
摘要
Abstract
In order to study the structure of complicated metro station seismic response features,combined with the seismic performance analysis of Shanghai Jiangwan metro station on the 10th line,several structural form is simulated by FLAC.The results show that when the cross-section form is symmetrical,the aseismatic ability of the metro station can be improved;when not,the aseismatic ability of the structure can be improved too if settlement joint is installed in the section of mutation;for the narrow subway stations,when the structrue is divided into several segments at a certain distance along the longitudinal seam seismic settings,the internal force can be reduced effectively in the metro station under seismic loading forces,and the aseismatic ability of subway station can be improved;the effect of the size of the hole in juncture is remarkable on the pillar in the hole and the continuous wall.关键词
