| 摘 要： | 根据超声回弹综合法测试原理,采用开封地区常用的混凝土原材料,制作了不同强度等级、龄期的混凝土试块,进行大量的综合法测试和抗压破损试验,并选用最小二乘法来拟合所测参数与实际抗压强度之间的关系,建立了开封地区超声回弹综合法专用曲线,并对该曲线进行了验证。

| Abstract: | According to the ultrasonic springback comprhensive measuring principle,the commonly-used concrete of Kaifeng area was used to make concrete samples with different strength and ages.Based on the concrete samples,many comprehensive measurment and anti-pressure and damage tests were made,and the least square method was selected to fit the measuring parameters and real anti-pressure strength.The ultrasonic springback comprehensive special curve of Kaifeng area was established and verifitied. |
