摘　　要：根据商品混凝土试件拔出力及抗压强度的测试数据,建立了深圳地区后装拔出法检测商品混凝土强度测强曲线。试验采取了一种简单有效的措施以控制成孔尺寸,从而保证了测强曲线的精度。该测强曲线已应用于深圳地区多项实际工程的商品混凝土强度检测工作中。Based on the data of pull-out fo rce and cube strength of commercial concrete specimens, the pull-out force-com pressive strength curve in Shenzhen was set up. A method was adopted to control the dimension of the center hole simply and effectively and the precision of the curve is consequently ensured. The curve has been applied in many engineering p rojects to test the strength of commercial concrete in Shenzhen.
