摘　　要：通过采用4.5J高强回弹仪对深圳地区不同工程强度等级为C55~C70的高强混凝土构件进行现场检测,对回弹检测所得到的强度换算值及在相应检测位置钻取芯样所得到的试件抗压强度进行对比。根据检测数据回归出关于深圳地区C55~C70的高强混凝土的专用测强曲线。Through the testing of high-strength concrete components with strength grade between C55 and C70 of different engineering in Shenzhen area,the strength conversion value obtained from concrete compressive strength testing using a 4.5J high-strength Schmidt hammer,and the compressive strength of specimens obtained from drilling core samples at corresponding testing positions were compared,and a dedicated strength testing curve for high-strength concrete of C55~C70 in Shenzhen was regressed.
