摘要
介绍了超声-回弹法测定混凝土强度的原理,利用非线性最小二乘法求得了大庆地区混凝度强度测定的超声-回弹法公式.
The principle of concrete strength measurement based on ultrasound-resilience method is introduced,ultrasound-resilience method formula of concrete strength measurement in Daqing district is obtained by using the nonlinear least square method.
