| 摘 要： | 文章结合大伙房输水隧洞二期工程,考虑围岩与衬砌层、水体与衬砌层的相互作用,采用现代岩体力学模型,对其进行模态分析和时程分析,分析了混凝土衬砌层的动力特性和地震响应,探讨了埋深、衬砌厚度、围岩弹性模量和水体等因素对混凝土衬砌层地震响应的影响;并指出衬砌层的环向应力是地震破坏作用的主导,埋深和围岩弹性模量是影响衬砌层地震性能的重要因素,衬砌厚度和水体的影响较小。

| Abstract: | Based on the 2nd phase Dahuofang water diversion tunnel project,taking the interaction of surrounding rock and lining,water and lining into consideration,modern rock mechanical models were adopted to conduct modal analysis and time-history analysis,and the dynamic characteristics of concrete lining and seismic responses were also analyzed.Meanwhile the influence of overburden,lining thickness,elastic modulus of surrounding rocks and water on seismic responses of concrete lining was discussed.Results showed ... |
