摘要： 超声波检测是弹性波测试方法中的一种，其理论基础建立在固体介质中弹性波的传播理论上，该方法是以人工激发振源的方法向介质（岩石，岩体，混凝土构筑物）发射超声波，在一定的空间距离上接收介质物理特性调制的超声波，通过观测和分析超声波在不同介质中的传播速度、振幅、频率等声学参数，解决岩土工程中的有关问题。

Abstract: The ultrasonic testing is one of the elastic wave tests, its theory is from the theory of elastic wave propagation in solid media. In this method, the ultrasonic wave is from the artificial excitation vibration source to some certain media, such as rock, rock mass and concrete, etc., and the wave modulated by their physical characteristic is received in some distance, then acoustic parameters of wave such as velocity, amplitude, frequency, etc. are observed and analyzed. By this way, some problems in geo-engineering are solved.
