Analysis of the Lining Structure of Water Conveyance Tunnel in a Reservoir
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.
