近年来,我国声波探测技术在岩体工程中已有广泛的应用。声波探测具有设备轻便,精度高以及理论比较成熟等优点。随着电子计算机科学技术的发展,国内外都开始将微处理机装入声波探测仪内,通过程序控制对声波作磁带记录或瞬态存贮和数字处理,使声测技术水平有很大提高。 目前,虽然对冻土声波数字处理技术(频谱分析)的研究,受耦合等条件所导致的测试误差的影响,还未得到广泛的应用。但是,从发展角度来看,用它进行冻土的研究和冻土工程的检测,前景十分广阔。
In recent years, sound wave detection technology in China has been widely used in rock mass engineering. Acoustic wave detection has the advantages of light weight, high precision, and mature theory. With the development of computer science and technology, microprocessors have been installed in sound wave detectors both at home and abroad, and sound recording technology has been greatly improved by recording sound waves for tape recording or transient storage and digital processing through program control. . At present, although the study of sound wave digital processing technology (spectrum analysis) of frozen soil, the influence of test error caused by coupling and other conditions has not been widely used. However, from the point of view of development, it is very promising to use it for the study of frozen soils and the detection of frozen soils.
