摘　　要：针对传统结构力学方法在输水隧洞复合式衬砌设计分析中不能真实地考虑初期支护和二次衬砌的荷载承担比例问题,以城门洞型隧洞为例,采用有限单元法对围岩的稳定性、初期支护和二次衬砌的应力状态进行了计算分析;并获得了二次衬砌作为承载构件时的围岩压力分担比例。The loading ratio of primary support and secondary lining can not be clearly defined when the traditional structural mechanics method was used to design the water tunnel.As an example,the stability of surrounding rock and the stress state of arched tunnel was analyzed.And the loading ratio was advised in this paper.
