| 摘 要： | 采用窗口取样法测量岩体中随机不连续面的迹长, 相对于无限二维空间的岩体而言存在着不可避免的偏差。因此, 在实际岩体工程中要对实地测量迹长的偏差进行校正, 以获得校正后的平均迹长。本文着重讨论了Kulatilake教授于 1984年提出的不连续面迹长均值估算法, 并对算法作了必要的修正, 使算法更客观, 更完善, 编制的计算机代码可以很方便地求取无限二维岩体不连续面的校正迹长。

| Abstract: | There existed deviation in determination of the discontinuity trace length in rock mass by using sampling window method, during the field sampling relatively to infinite two-dimensional rock mass. Therefore, the field sampling deviation of trace length has to be corrected in real rock engineering to get the corrected mean trace length. the sampling window method proposed by Prof. Kulatilake in 1984 is briefly reviewed and some modification of it is proposed in this paper. the improved method is more reliable and perfect in calculation. It is convenient to obtain correct discontinuity trace length in infinite two-dimensional rockmass by means of computer program. |
