三维有限元分析计算在迈湾水利枢纽工程大体积异形混凝土结构配筋中的研究及应用OA

The Maiwan dam inlet adopts a stacked beam gate for stratified water intake.The inlet follows the flow direction as follows:trash rack section,stacked beam gate section,rapid accident gate section,inlet section,and transition section.The internal force calculation and analysis of the intake structure were carried out by using the three-dimensional finite element method,and the cross-sectional stress graph of the structure in the elastic stage was obtained.Reinforcement was configured according to the elastic principal tensile stress graph,solving the problem of difficulty in calculating the reinforcement ratio of large volume irregular structures under complex stress conditions using traditional analytical methods.The calculation results can be used for similar engineering discussions and references.
