某水电站引水隧洞三维非线性有限元分析

Three-dimensional nonlinear finite element analysis of a hydropower station diversion tunnel

引水隧洞是应用较为广泛的地下工程形式,整体结构更为复杂,基于传统的结构计算方法显然不具有可行性,无法准确反应衬砌与围岩的受力关系。对此,文章以某水电站引水隧洞为背景,利用有限元数值模拟的方式,探讨隧洞稳定状况,总结结构的受力特点,突破了传统计算方法的局限,具有一定的参考价值。

Diversion tunnels are widely used forms of underground engineering,and the overall structure is more complicated.Traditional structural calculation methods are obviously not feasible,and they can’t accurately reflect the stress relationship between the lining and surrounding rocks.In this regard,the article takes the diversion tunnel of a hydropower station as the background,and uses the finite element numerical simulation method to explore the stability of the tunnel,summarizes the structural characteristics of the force,breaks through the limitations of traditional calculation methods.
