| 摘 要： | 在进行不连续面3-D网络模拟过程中, 不连续面的大小是一个重要的参数, 该数据主要来源是在现场露头上测量不连续面出露的迹长。由于取样中不可避免的偏差而使结果有误差, 在进行平均迹长估计时取样的误差必须予以校正, 本文介绍一种用概率的方法考虑取样误差通过有限2-D露头上测量的不连续面数据求算无限2-D空间平均迹长的技术。该方法可以借助计算机进行处理。

| Abstract: | In the process of 3-D net work Modelling of discontinuities, the size of discontinuities is an important parameter. This parameter is mainly come from measuring the trace length in-situ. Sampling errors can occur due to the bias, these errors need to be corrected for the estimation of mean trace length. The method introduced here takes sampling errors into account by probability theory and through the traces data from finite 2D window transfor to trace length in infinite 2-D space. By means of computer, it is easy to estimate the mean trace legnth. |
