| 摘 要： | 采用无限元作为岩体地下洞室静动力分析的边界条件,建立了岩体地下洞室的静动力有限元一无限元(FE-IE)计算模型,分析了柔性垫层对水电站厂房这类大型岩体洞室结构的减震效果.研究结果表明:柔性垫层虽未能从根本上改变岩体洞室结构的地震响应,但是设置一定厚度的柔性垫层后不仅能充分发挥岩体洞室围岩的自承能力,而且还能明显地减小混...

| Abstract: | An FE-IE model is set up for the stability analysis of large underground rock cavern by using infinite elements as the static and dynamic boundaries.On the basis of this proposed static and dynamic FE-IE model,the research on the seismic resistance of soft-seismic absorption layer for large rock cavern is performed.The simulated results show that although the seismic absorption layer couldn't essentially change the dynamic response of rock cavern,it not only can fully utilize the self-supporting ability of ... |
