摘　　要：目的解决在实际工程中如何进行粘钢加固粘结界面抗剪强度检测方法及检测评定标准问题.方法通过在混凝土强度等级为C60和C90的基材上粘贴等宽变长的钢板,进行粘钢加固粘结界面抗剪承载力试验,并根据试验结果对现场检测时的取样尺寸、检测评定标准进行研究.结果提出了一种现场检测粘结界面抗剪强度的方法,确定了检测时的取样尺寸(40 mm×40 mm)与检测评定标准.结论这种方法简单可行,对粘钢加固技术的发展及工程质量控制具有重要的意义.In order to measure the adhesive strength of the adhesive layer and specify the measuring standard in practical engineering during the experiment of measuring the carrying capacity, the steel plates with the same width and different length are glued to the concrete with the strength grade C60 and C90. The size of the test specimen and the measuring standard are studied according to the experimental result. Thus, a method of field measuring the adhesive strength between the steel plate and the concrete is put forward, and the size of the test specimen and the measuring standard are specified. Easy as the method is, it will play an important part in developing strengthening technology by gluing steel plate and controlling the engineering quality.
