圆形有压隧洞混凝土衬砌结构计算方法的比较

水电站圆形有压隧洞钢筋混凝土衬砌常用计算方法有公式法、弹性力学法、边值法及有限元法等,但这几种方法计算结果常常相差较大,笔者分析了计算结果相差较大的原因,对这几种计算方法进行了初步分析评价。

Comparison of calculation methods of concrete lining structure for circular pressure tunnel

For reinforcement concrete lining of circular pressure tunnels,the common calculation methods are formula method,elastic and mechanical method,boundary value method and finite element method,but the calculated results of those methods are greatly different.The paper analyzes the reasons of great differences,and gives a preliminary evaluation on the mentioned methods.
