摘　　要：以原位单剪试验结果来论述原位单剪试验法检测混凝土抗压强度技术的原理和特点。原位单检试验法是在混凝土结构面上钻直径44 mm、深度40mm的芯样,不需取出,将装有左右卡头的剪切头套住芯样后,通过施加剪力将混凝土芯样在深度25 mm处剪断,用混凝土剪切强度推定混凝土抗压强度的一项新的混凝土抗压强度检测技术。The test result of simple shear was introduced to discuss the technical principle and characteristics of simple shear test for compressive strength of concrete. Simple shear method is a new test method for concrete compressive strength, using the shear strength of concrete to deduct the compressive strength. This method drills a core of 44mm diameter and 40mm depth on the surface of concrete structure, but doesn＇t draw it out, and then covers a shear head equipped with chuck on the left and fight sides on the core to apply a shearing force and to cut off the core at 25mm depth.

关 键 词：原位单剪法 混凝土剪切强度 混凝土抗压强度 强度等级 节能
