摘要

以位于地震断裂带的水电站出线水平井为项目背景,利用大型有限元软件进行三维模拟,考虑土与结构的相互作用,研究分析地震作用下的超深水平井的动态响应。分析表明:水平井在竖向地震作用下的动力响应比在水平地震作用下的小;周围土体对结构的位移限制,以及深厚覆盖层对地震波的吸收,使得水平井无论是水平地震作用还是竖向地震作用下,动力响应都很小,表明水平井的抗震性能优越,证实了深埋结构的抗震可靠性。
Based on the example of the horizontal well of hydropower station,the full three dimensional finite element model was used to analyze dynamical response of the deep-embed horizontal well under seismic action.Interaction between the structure and the soil had also been taken into account in calculation.The results indicated that the horizontal well dynamic response of vertical earthquake was less than that of horizontal earthquake.And the dynamic responses were small both on vertical earthquake and horizontal earthquake due to the displacement restriction of soil around and seismic wave absorption from the soil,which proved the earthquake-resistance reliability of deep-embed structure.
