| 摘 要： | 某20层框架剪力墙结构办公楼位于7度抗震设防区,在施工至第10层时,发现第4层4片墙柱混凝土强度严重偏低,不能满足原设计C40的强度要求。经过比选,确定采用分批置换混凝土法进行加固,通过合理布置临时支撑,采用具有早强、高强、自流性的灌浆料浇筑,并对加固过程进行全程监测,取得良好的加固效果。

| Abstract: | A 20-story office building of frame-shear wall structure was being built in 7 degree area. When the 10th floor was being built, it is found that 4 wall-columns＂ grade of concrete strength was less than C40 in the 4th floor. The concrete-replacing method was used to solve this problem. The effect of reinforcement is good with the reasonable temporary supports and the grouting material which is early-strength, high-strength and flow automatically. All of the reinforcement process was in the monitoring. |
