| 摘要： | In this paper three-dimensional seismic dynamic responses of tunnel portal are modeled by FLAC.Seismic response rules of tunnel lining and rock mass are acquired from calculating.Some conclusions are presented as follows:(A)Rules of Displacement:the displacement peak obviously lags behind earthquake action,that means that the displacement values caused by seismic dynamic response will come to maximize after the maximum acceleration caused by earthquake action. |
