APPLICATION OF HIGH-FREQUENCE ULTRASONIC WAVE TECHNOLOGY TO TECTONO-PETROLOGY--TAKING CAOHU AREA OF SOUTH PART OF TANCHENG-LUJIANG FAULT BELT AS EXAMPLE
高频超声波技术在构造岩石学研究中的应用--以郯庐断裂带南段巢湖地区为例

A new method using high-frequency ultrasonic wave technique to the study of structural geology is presented. The relationship between wave velocity and stress in rocks is discussed,and the state of stress distribution in the core parts of anti-cline is presented. The study results show that the ultrasonic wave technology is a possible tool for the study of tectono-petrology. The distributions of wave velocity have close relation to that of stress quality in the deformed rocks. The stress distributions in Fenghuangshan anti-cline obtained by wave velocity are of the same rule with the theoretic deduction. With the ultrasonic wave technique,the distributions of the stress state and the strongest locations can be easily and accurately determined,which is very helpful to the study of tectono-petrology as well as the practice of engineering geology. Comparing with the other methods of studying tectono-petrology,the ultrasonic wave technique is of merit of simple control and high accuracy.
