摘　　要：在传统设计理论提出堵头结构初步设计成果的基础上,使用大型通用有限元软件ANSYS,分析导流隧洞堵头结构在封堵工况下的应力、变形分布规律,并采用整体安全系数法进行堵头结构的整体抗滑稳定分析;然后,对初步设计的堵头结构进行优化设计,使堵头结构更加经济合理。结果表明,有限单元法对采用传统设计方法得到的堵头设计成果具有较大的优化作用,可以为堵头设计方法的改进提供参考。Based on the results from the traditional design theory of diversion tunnel plug, analysis of the stress and deformation characteristic of the diversion tunnel plug has been carried out by using the large-scaled universal FEM software ANSYS, and the integral slide-resistance stability of the plug structure has been analyzed through the integral safety factor method. According to the resuits of the finite element method, optimization design of the plug structure has been done to make the plug structure more reasonable and economical. The results show that the design of diversion tunnel plug structure with the finite element method is superior to the traditional method, and this research has reference effect for other design of diversion tunnel plugs.
