joint spacing

According to the basic principles of Bieniawski's geotechnics rock classification, a classification of stope stability is established on the basis of five parameters, i.e. unia-xial compressive strength, RQD, joint spacing, joint state and underground water conditions.

本文根据Bieniawski的地质力学岩体分类法的基本原理，基于岩石的单轴抗压强度、RQD、节理间距、节理状态和地下水条件等五个参数，定出一种采场稳定性分类方法。

The comparison between the damage model and the jointed element model is performed as well as the analyses of different joint angle, different joint spacing, different joint length etc with the damage model;

用所编写的程序与节理有限元法做了大量的对比，并对不同的节理倾角，不同的节理间距，不同的节理长度等情况进行了分析。
