摘　　要：介绍了超声法测试的原理及其在桩身质量测试中的应用,通过分析研究记录下来的波动信号,确定桩身的力学特性,了解它们的内部缺陷,工程实例表明,这种方法是一种高精度、使用方便、在岩土工程领域具有广阔应用前景的方法。In this paper, a kind of new measure named ultrasonic method as well as its principle and the application in pile quality testing are in- troduced. Ultrasonic method determines the mechanical character and concrete defects of piles by analyzing recorded fluctuate signal. Projects show that it is a kind of high-precision and easy-to-use method with extensity prospect in geotechnical engineering.
