摘要
根据理论和实验研究结果,提出了用超声技术研究地质构造的新方法,以便定量地确定产生褶皱断裂的区域应力场。岩石在受压方向的波速一般大于拉张方向的波速。介绍了应力各向异性系数的概念及制作应力椭圆的方法,这有助于构造分析或成矿预测研究。
Based upon the theoretical and experimental results obtained,a new method is proposed for thestudy of geclogical structures by the measurement of ultrasonic wave velocities measurement in rocksupon samples,in order to make a quantitative d termination of the regional stress field by whichfolds and fractures are formed.By the fact that the wave velocity in compression direction is greaterthan that in tension direction,the concept of anistropy factor of stress and the stress ellipse drawingmethod are introduced.They are helpful to tectonic analysis and metallogenic prognosis.
