摘要
迈湾水利枢纽坝式进水口采用叠梁门分层取水,进水口顺水流向依次为拦污栅段、叠梁门段、快速事故闸门段、进口段及渐变段。采用三维有限元法对进水口结构进行内力计算分析,获取结构在弹性阶段的截面应力图形,按弹性主拉应力图形配置钢筋,解决了使用传统解析法结构计算大体积异形结构复杂受力条件下的钢筋配比困难的问题,其计算结果可供类似工程探讨和参考。
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.
