摘　　要：对于采用常规无损检测手段无法实施定量检测的大体积水工混凝土结构体,利用稳态表面波技术可以实现其各项特性参数的获取。本文系统介绍了稳态表面波技术的原理和检测系统,并通过检测实例介绍了稳态表面波技术及其在大体积水工混凝土质量和裂缝深度无损检测等方面的应用进展。实践证明,稳态表面波检测技术抗干扰能力强,检测精度较高。For the massive hydraulic concrete structure that cannot be quantitively detected with the conventional means of nondestructive testing,all the characteristic parameters of it can be obtained with the steady surface wave technology. The principle and the testing system of the steady surface wave technology are systematically introduced herein,and then the advance of the technology and its application to the non-destructive testing on the quality and cracking depth of the massive hydraulic concrete are described through the testing cases concerned. The practice shows that the anti-interference capacity of this technology is strong with higher testing accuracy.
