【摘要】 地下隧洞抗震研究是当今地震工程界重要的研究课题。针对某地下隧洞工程,利用拟静力方法对隧洞在地震作用下的抗滑稳定性进行了校核,并结合串联系统的可靠度理论对隧洞进行了动力可靠度分析,对在役隧洞的抗震风险做出了初步评价,供隧洞地震稳定性分析和工程安全评估工作参考。更多还原

【Abstract】 Research on seismic resistibility of underground tunnel is an important issue in today’s earthquake engineering field.For an underground tunnel project,anti-slide stability of tunnel under earthquake force is verified using pseudostatic approach and the theory of series system is used to analyze dynamic reliability of tunnel.Risk to seismic resistibility of service tunnel is evaluated preliminarily.A reference is provided to analysis of seismic reliability of tunnel and security assessment of project.更多还原
