摘要:

摘要:  基于超声波无损检测理论,建立了超声波检测混凝土结构强度的预测方法.以吴淞导堤表面混凝土质量检测为案例,比较分析了4 200个

超声波法预测的和400个现场钻孔取芯实测的混凝土强度值.结果表明,混凝土强度实测值和预测值均近似服从正态分布,概率峰值区间分别位于
12~16 MPa和9~15 MPa,分布密度分别为28%和23.26%,强度分布区域均为3~25 MPa,且均小于设计值,预测结果和实测值吻合度较高.

Abstract:

Abstract: Based on the theory of ultrasonic nondestructive testing, a prediction method for the strength of concrete

structures using ultrasonic testing was established. The predicted strength of concrete with 4 200 measuring points using
ultrasonic testing and measured strength of concrete with 400 samples using field drilling for core tests were compared
based on the background of Wusong Jetty. The results show that both of the predicted and measured strength are
approximate normal distribution. The probability peak intervals of the two methods are 12 to 16 MPa and 9 to 15 MPa, the
distribution density are 28% and 23.26%, the range of strength distribution are 3 to 25 MPa and both are smaller than the
design value. These results show an overall good performance by the prediction method.
