摘　　要：为解决钢板组合剪力墙界面脱空缺陷检测的问题,在混凝土自身产生水化热的基础上,利用钢板与混凝土自身所形成温差对钢板组合剪力墙界面脱空缺陷进行红外热成像法检测。研究结果表明:在混凝土水化热条件下可以有效识别出钢板组合剪力墙界面脱空的缺陷位置和尺寸,入模温差在15℃时,可识别出面积为1 cm^(2)以上的脱空缺陷,当入模温差在10℃和5℃时,可识别出面积为4 cm^(2)以上的脱空缺陷。这种方式对工程检测更加方便快捷,便于在浇筑混凝土时进行实时跟踪检测。具有更高的实际应用价值。In order to solve the problem of interface void defect of composite steel plate shear wall,based on the hydration heat of concrete itself,infrared thermal imaging method was used to detect the interface void defect of composite steel plate shear wall by using the temperature difference between steel plate and concrete itself.The results showed that:under the condition of concrete hydration heat,the defect location and size of the interface void of composite steel plate shear wall could be effectively identified.When the temperature difference during molding was 15℃,the void defect with an area of more than 1 cm^(2) could be identified.When the temperature difference during molding was 10℃ or 5℃,the void defect with an area of more than 4 cm^(2) could be identified.The method could be more convenient and fast for engineering detection,and could be convenient for real-time tracking detection when pouring concrete.It showed higher practical application value.
