摘要
本文精测了新疆塔里木北部地区压、张、扭三类不同性质断层断面的起伏高度和长度,利用谢和平及Parisean(1994)的公式,测算了断面分维数D,又由D值测算了粗糙度JRC值,发现压、张、扭三类断层的D和JRC值有明显差别,所取得D值与美国的San Andrees断层的D值具有一定的相似性。
The author have measured the relief length and height of fault planes of compressive, tensile and shear origins in northern Tarim, Xinjiang, and determined the fractal dimension D values using the formula established by Xie Heping and W. G. Parisean (1994) and then calculated the joint roughness coefficent (J.RC) values of different fracture structure planes according to the D values. It is found that the D and JRC values of compressive, shear and tensile faults are notably different and that the D values obtained by the authors are somewhat similar to those of the San Andrees fault in the United States.
