摘　　要：水工隧洞是埋藏于岩体的地下结构,所处的环境与地面结构存在很大的差异性。其结构受力、边界条件的复杂性使得很难用传统的结构分析方法分析在各种工况下衬砌的工作特点。采用有限元法和边值法对混凝土衬砌在运行期、检修期以及施工期的应力变化规律进行研究,并与混凝土结构的允许应力值进行对比,分析两种方法结果的差异性。Hydraulic tunnels are underground structures buried in rock masses,and their environment differs greatly from the ground structure.The complexity of its structural stress and boundary conditions makes it difficult to analyze the working characteristics of lining under various working conditions using traditional structural analysis methods.This paper uses finite element method and boundary value method to study the stress variation law of concrete lining during operation,maintenance,and construction periods,and compares it with the allowable stress value of concrete structures to analyze the differences in the results of the two methods.
