齐热哈塔尔电站尾水渠高扶臂式挡墙结构设计

Structural Design of High Buttressed Retaining Wall of Tailrace Channel of Qirehata'er Hydropower Station

采用有限元的方法,对齐热哈塔尔电站尾水渠挡墙不同工况进行了整体分析与计算。通过对墙底不同基础弹性模量的敏感性分析,并对比规范及理正计算结果,得出了对于基础弹模较小的挡土墙结构设计时,应考虑墙体的空间变形协调,并对挡土墙底板和肋板合理配置受力钢筋,对类似工程的高扶臂式挡墙的结构设计有一定的借鉴作用。

Integral analysis and calculation are carried out to the retaining wall at tailrace channel of Qirehata'er Hydropower Station with finiteelement method.After sensitivity analysis of the wall base with different elastic modulus and comparison of the specifications and Lizhengsoftware calculation results,it draws a conclusion that the space deformation compatibility of retaining wall shall be considered and stressedreinforcement shall be arranged on the bottom plate and ribbed plate the retaining wall with small foundation elastic modulus.This can provide some reference for structural design of high buttressed retaining wall of similar projects.
