【摘要】 综述了近几十年来地下结构地震破坏机理及其反应特点,并阐明了不同类型的地下结构由地震所引发的震害形式各异。对当前地下结构主要的抗震研究方法进行了概括,并分别从解析法、数值模拟、模型试验等方面,全面回顾了地铁地下结构抗震性能研究的进展。同时,指出了目前在地铁地下车站抗震存在的问题和缺乏考虑之处,并提出未来研究方向。更多还原

【Abstract】 The earthquake failure mechanism and response characteristics of underground structures in recent decades were reviewed,and the different forms of earthquake damage caused by different types of underground structures were explained.In this paper,the main seismic research methods of underground structures were summarized,and the research progress of seismic performance of metro structures was reviewed from the aspects of analytical method,numerical simulation and model test.At the same time,it pointed out the existing problems and the lack of consideration in the seismic resistance of metro underground stations,and put forward the future research direction.更多还原
