地铁地下结构抗震设计方法差异性规律研究
|
摘要
详细介绍动力时程分析方法、反应位移法、整体式反应位移法、强制反应位移法、张建民地震土压力方法、简化地震土压力方法、反应加速度法、地下结构Pushover分析方法等地铁地下结构抗震设计方法。结合以上各种抗震设计方法,计算不同地质条件以及不同埋深条件下北京地下直径线单层框架结构侧墙变形(顶底板位移差值)及结构内力,并对其结果进行比较分析,为探讨各种设计方法计算结果的差异性规律提供一定的依据。结果表明,不同土层条件时,反应加速度法、地下结构Pushover分析方法与动力时程分析方法计算值基本一致;不同埋深条件时,基于日本铁路抗震设计规范动弹簧系数的反应位移法、张建民地震土压力方法与动力时程分析方法计算值更为接近。
Different seismic design methods for subway structures are introduced,including dynamic time history analysis method,response displacement method,integrated response displacement method,modified cross section racking deformation method,Zhang Jianmin's seismic earth pressure method,simplified seismic earth pressure method,the response acceleration method and Pushover analysis method.The deformations(displacement difference between the roof and floor) and the internal forces of single-frame side wall of underground diameter line in Beijing in different geological conditions and different depths are computed with above design methods and compared with each other,which can provide some reference for the difference law of results with various design methods.The results show that the calculated values of response acceleration method,Pushover analysis method agree well with dynamic time history analysis method in different soil conditions.In different depth conditions,the calculated values of response displacement method based on the Japanese seismic design of railway dynamic spring constant and Zhang Jianmin's seismic earth pressure method approach more to dynamic time-history analysis method.
