摘要
采用ANSYS软件对引水发电隧洞上平管段洞室开挖支护和运行荷载条件下的变形和应力进行了二维有限元计算,根据计算结果分析了不同荷载组合对洞室围岩稳定性的影响,并提出了相应的优化支护方案,对设计和施工具有一定的参考价值。
Reformation and stress of excavation support flat pipe section of hydropower tunnel under operational loading condition are calculated by two-dimensional finite element calculation using ANSYS calculation software. Based on calculation results effect of various loading combination on rock caverns of tunnel is analyzed, and the corresponding optimized support scheme is proposed. It is valuable for other design and construction.
