盾构隧道横向抗震设计分析方法与验证
|
摘要
随着地下空间大规模的开发和利用,建立地下结构的抗震设计规范已迫在眉睫。目前国内外学者在隧道的横向抗震分析方面提出了多种分析方法,包括地震系数法、相对刚度法、BART法、响应位移法、St.John法、Shukla法、Penzien法等,但这些方法均有其各自的局限性。文中主要介绍了上海市《地基基础设计规范》推荐的简化分析方法及响应位移法。同时,结合隧道地震响应的离心模型试验,验证了响应位移法的可行性与合理性。
With the large-scale development and utilization of underground space,it is extremely urgent for developing seismic design code of underground structures.Many approaches dealing with the lateral seismic problem of tunnels have been developed by scholars at home and abroad,including seismic coefficient method,relative stiffness method,BART method,response-displacement method,St.John method,Shukla method,Penzien method and so on.But these methods have their limitations.Simplified analysis method of foundation design code of Shanghai and response-displacement method are mainly introduced in this paper.Meanwhile,on the basis of centrifugal test for seismic response of the tunnel,it is verified that the response-displacement method is feasible and rational.
