摘　　要：剪切法包括:原位单剪法、分段单剪切法和抗剪法(芯样双剪法)等,它是利用混凝土自身的剪切强度换算混凝土抗压强度,可以用于泵送混凝土、早龄期混凝土以及既有结构混凝土强度检测,是目前唯一一个不受构件形状、表面平整度、粗糙度影响、不需要对试件进行二次加工,既可以原位,也可以体外检测的技术,它可检测受损混凝土构件强度,可作为超声波探伤的一种补充,预计该方法是具有一定推广价值的检测新技术。The shearing method including single cut in situ method, segments of single shearing and shear method （dual core samples cut metbod）,it utilizes concrete in terms of their shear strength of concrete in compression can be used pumping concrete, early age concrete and concrete strength of existing structures, is currently the only one shape, the surface flatness, roughness of components from, does not require secondary processing specimens, both in situ and to be in vitro testing technology that can detect damage to the strength of concrete structures can be used as a complement to ultrasonic flaw detection, the process is expected to detect new technologies to promote a certain value.
