摘要: 引水隧洞作为一种典型的地下工程,结构复杂、地质多变,采用传统的结构计算方法已无法全面反映衬砌结构与围岩的联合受力特征。以立洲水电站引水隧洞为例,运用有限元数值模拟对隧洞围岩稳定性及结构的受力特性进行研究,较好地解决了传统算法存在的问题,供类似项目计算时参考。

Abstract: The structure of the diversion tunnel, which is a typical underground engineering, is complex; and the geology condition of the tunnel is various. Therefore, it is cannot reflect the combined force characteristics of the lining structure and the surrounding rock completely by means of the traditional structure calculation method. Taking the diversion tunnel of the Lizhou Hydropower Station as example, using the finiteelement numerical simulation method, the stability of the tunnel surrounding rock and the force characteristics of the structure were researched. The problems existing in traditional algorism were solved well. The method of this paper can be used as reference for calculation of similar projects.
