运用CT技术探测岩石标本三维速度结构的方法

A Method of Investigating Three Dimension Velocity Structure of Rock Sample by CT Technique During Deformation Process

本文讨论运用超声探测技术及计算机层析技术探测岩石标本在变形过程中的三维速度方法.运用卷积反投影重组法对标本波速图象进行重建,用理论数据对方法进行了检度结构检验和误差分析,为实际探测提供基础.数值模拟结果表明,本文提出的方法具有一定的实际应用意义.

In this tutorial paper the method of invesigating three-dimension velocity structure of rock sample by AE technique and the computerized tomography are described. The convolution backprojection algorithm is used to reconstruct an image of the internal velocity structure of rock sample which has been created by certain formation history. The method is tested and analysed by synthetic data. The numerical result shows that this method is significant in practical application.
