某水力发电厂已建主厂房为钢筋混凝土框架结构。在施工期间,当混凝土浇注至D号发电机楼层时,因故混凝土浇注中断,造成其中6根大梁出现水平向混凝土冷缝。经采用叠合面抗剪的计算方法对冷缝面的抗剪承载力进行验算,结果表明,混凝土冷缝面的抗剪承载力明显不足,需要补强处理。之后,依据分析结果及有关规范进行粘钢补强加固取得了较好的效果。
某水力髮電廠已建主廠房為鋼觔混凝土框架結構。在施工期間,噹混凝土澆註至D號髮電機樓層時,因故混凝土澆註中斷,造成其中6根大樑齣現水平嚮混凝土冷縫。經採用疊閤麵抗剪的計算方法對冷縫麵的抗剪承載力進行驗算,結果錶明,混凝土冷縫麵的抗剪承載力明顯不足,需要補彊處理。之後,依據分析結果及有關規範進行粘鋼補彊加固取得瞭較好的效果。

The main building of a power plant was the reinforced concrete frame building.The concrete infusion of D\+# electric generator was interrupted during construction,some horizontal inside interfaces appeared in six beams.The anti-shear capacity of the concrete inside interface was checked with the computational method of composite interface anti-shear.The results showed that the anti-shear capacity of concrete inside interface was insufficient obviously,which needs to be reinforced.Consequently,the steel-bonding reinforcement was adopted according to analytical results and relevant standards,and the results were effective.
