国内工程CT技术的发展与应用

DEVELOPMENTS AND APPLICATIONS OF ENGINEERING CT TECHNOLOGIES

计算机层析成像(Computerized Tomography,CT)是一种有效的地球物理手段。由于CT具有信息量大、分辨率高等优点,使其中工程领域具有特殊的优势。近年来,各种CT技术在工程地质勘察、建筑物无损检测等工程领域得到了广泛的应用,取得了大量的成果。目前常用的工程CT技术包括弹性波CT、电磁波CT、电阻率CT三大类。本文对这三种技术的技术特点、关键技术和应用实例分别进行了概括性介绍。

A general introduction of the characteristics, imaging methods and applications of three major kinds of CT is given in this paper. Computerized Tomography （CT） is an impactful and useful geophysics method. CT can provide much more information and higher resolution. In recent years, several kinds of CT methods, such as elastic wave CT, electromagnetic wave CT and resistivity tomography, are widely used in engineering geological investigation, nondestructive test and so on.
