| 摘 要： | 采用大型商业有限元软件ANSYS对云南某电站的水工隧洞地震响应进行了数值模拟.通过分别从X方向与Y方向输入地震激励,发现X方向的激励对隧洞的影响较大,隧洞衬砌的最大位移发生在隧洞中段拱顶区,得出的结果对实际工程有一定的指导意义.

| Abstract: | The seismic dynamic response to a tunnel of hydroelectric station in Yunnan province is analyzed by ANSYS finite-element software.The results that the effect of X direction is more powerful than Y direction,and the biggest displacement of tunnel lining occurs on the middle top of the tunnel,is found by inputting seismic stimulation from X and Y direction.The conclusion is meaningful to the actual projects. |
