【摘要】 自阪神地震后,地下空间结构的抗震设计问题已越来越受到人们的重视。通过对历次地震中地下工程震害情况的介绍,总结各类地下结构震害的特点;结合上海地铁某车站方案设计的计算结果,分析地下连体结构的抗震能力及其抗震设计要点;介绍设计中常用的几种抗震设计计算方法,提出根据地下建筑使用功能和重要性的差异确定其抗震设防目标的理念,并对地下结构的抗震构造措施进行阐述。更多还原

【Abstract】 Increasing attention has been paid to the seismic design of tunnels and underground structures since the Osaka-Kobe Earthquake.In this paper,the seismic damage of various underground structures are presented and the characteristics of the damage are summarized.The seismic capacity and the key seismic design points of integrated underground structures are analyzed based on the calculation data of a station of Shanghai Metro.Several widely-used seismic design calculation methods are introduced,and the idea of setting the seismic fortification target of underground structures on the basis of their functions and importance is proposed.The seismic countermeasures for underground structures are also discussed.更多还原
