摘要
对于引水隧洞的衬砌计算．一般多采用结构力学程序法计算．当洞室围岩达到三类时一考虑围岩和衬砌的整体承载作用，采用有限元方法计算衬砌结构．所得的配筋率降低较多，投资效益显著。本计算方法有待在实践经验的基础上进一步完善修正。
The structural mechanics is usually adopted for the calculation of diversion tunnel lining. In case of the surrounding rock of classification Ⅲ, the finite element method is used to calculate the lining structure with considering of the holistic carrying capacity of surrounding rock and lining. Thus, the quantity of reinforcing steel bars for the project decreases and show the significant benefits. The calculation method used for the study are expected to be modified on the basis of practical experience.
