曲线隧道的震害机理及抗震分析方法探讨

Probe into Mechanisms of Seismic Disasters of Curved Tunnels and Seismic Analysis Methods

隧道震害的大量出现引起人们对隧道抗震研究的重视。分析曲线隧道的震害特性及震害机理,论述曲线隧道抗震分析的实用方法,提出曲线隧道在抗震分析中需要注意的问题,以期对曲线隧道的抗震研究提供参考。

Occurrence of a lot of seismic disasters in tunnels arouses emphasis of people on seismic research of tunnels. This paper analyzes properties and mechanisms of seismic disasters in curved tunnels, expatiates practical methods of seismic analysis of curved tunnels, and proposes problems that should be noticed in seismic analysis of curved tunnels with expectation of providing references for seismic research of curved tunnels.
