探索介绍一种浅槽粘贴钢板条加固薄壁闸墩的设计方法。通过裂缝检测及工程力学验算发现近尾洲水电厂 泄洪闸薄壁闸墩存在安全隐患, 为此提出了浅槽粘贴钢板条加固处理方案, 并采用有限元仿真对加固方案进行优化 设计。由于5混凝土结构加固设计规范6GB 50367- 2013 未收录过类似方法, 因而其设计与施工经验可为类似的加 固工程提供新的思路, 为水工建筑工程加固处理提供参考。

This paper intro duces the design method to r einforce the thin wall sluice pier by pasting the steel bar to the sha llow gr oov e. Thr ough the crack detectio n and eng ineer ing mechanics calculation, a safety haza rd w as found in the t hin wa ll pier of sluice gate in the Jinweizhou hy dr opow er plant. T he reinfo rcement scheme o f shallow gr oov e paste steel bar was pr oposed to so lv e t he pro blem, and finite element simulatio n w as per formed fo r the o ptimal design o f reinfo rcement scheme. No similar ap2 pro ach has been included in The Reinfor ced Concrete Structure Design Code GB 50367- 2013, ther efo re the pro po sed desig n met ho d can pr ov ide new ideas and r eference fo r the reinfo rcement o f hydraulic str ucture engineer ing pro jects.
