摘　　要：在水工隧洞衬砌配筋计算分析中,通过DL/T 5195—2004《水工隧洞设计规范》配筋计算公式计算,在部分情况下钢筋配筋量为负值,与实际不相符,本文通过改进规范配筋公式,提出一种内力叠加公式法,并把其配筋结果与有限元法和边值法进行对比验证,三种方法结果拟合度很高,证明了内力叠加公式法的可行性。In hydraulic tunnel lining reinforcement calculation analysis,through the DL/T 5195—2004《specification for design of hydraulic tunnel》reinforcement calculation formula,some cases steel reinforcement amount is negative,and inconsistent with actual.This paper proposes a method of internal force superposition formula,and its reinforcement result compared with finite element method and boundary value method validation,the fit of the three methods result is very high,prove the feasibility of internal force super position formula method.
