摘　　要：水电站工程中的引水隧洞多为圆形有压洞,其混凝土衬砌结构的计算方法主要有基于设计规范的有压隧洞设计方法和基于有限元法的有压隧洞设计方法。实际工程中,分别采用这2种计算方法进行设计时,其结果往往相差较大。针对某水电站工程圆形有压引水隧洞,分别采用上述2种计算方法进行衬砌结构计算,通过对比所得计算结果产生的差异,结合基本原理和基本假定分析产生的原因,并给出了相应建议。The diversion tunnels of hydropower stations are generally circular pressure tunnels,and the commonly used calculation methods of reinforced concrete lining are mainly pressurized tunnel design method based on design specifications(referred to as formula method)and based on finite element method(referred to as finite element method).In practical project,when these two calculation methods are used for design,the results are usually quite different.In this article,combined with the circular pressure diversion tunnel of a hydropower station project,the lining structure is calculated by formula method and finite element method respectively.By comparing and analyzing the differences between the calculation results obtained by the two methods,the reasons for the differences are analyzed according to the basic principles and basic assumptions,and corresponding suggestions are given.
