摘　　要：在混凝土试件上钻出规定直径和深度的芯状直拔试件,用专用的设备将其拔出,得到拔断的应力值,通过该应力值与同条件试块抗压强度之间的对应关系,建立直拔法检测混凝土强度测强曲线。During the experiment we first drill a cylinder specimen with specified diameter and depth and then pull it out with the help of special equipment.As the specimen is pulled out,the stress value can be tested.After comparing the relationship between the stress value and the compression strength of the test sample in the same conditions,we can set up the concrete strength curve tested by the pull-out method.

关 键 词：直拔法 混凝土强度 测强曲线
