用统计窗法确定岩石节理规模

To Determine the Scale of Rock joints by Statistic Method

在有限的露头上测得的节理几何参数是有偏差的。本文在假设节理形态呈圆盘的前提下,给出了无偏节理的方位频数、频率和迹长,以及迹长与圆盘直径的关系式,最后给出了实例。

Joint geometric parameters measured on finite outcrops are with deviations.The correct orientation numbers of joints, frequency and trace length and relation expression between the trace length and disc for discontinuities are given under the prerequisite that the pattern of joint is assumed to be a disc. Finally, a practical example is presented in this paper.
