| 摘 要： | 结构面间距是反映结构面分布特征的重要指标之一,也是工程岩体质量级别划分的重要指标之一。与传统的结构面间距定义不同,本文认为只需按组测量结构面之间的间距同样可以分析结构面分布特征,并给出了结构面类型的4类划分法,依此建立结构面序列,利用时间序列的自回归滑动平均模型建立节理间距的AR IMA模型,提出了间距序列建模和模型检验方法,并以实例印证了AR IMA模型表示间距序列是合适的。

| Abstract: | The space of discontinuities is one of important indexes which explains the distribution of discontinuities and also classifies quality of engineering rock mass.Unlike the traditional definition of discontinuities space,this paper points out that the distribution of discontinuities can be analyzed as long as the spaces of neighboring discontinuities are measured.It presents the four-type methods of classifying discontinuities to built the discontinuities series.It set up an ARIMA model of discontinuities space by means of theory of time series and provided methods of building and checking model.An actual case is studies to show that the ARIMA model is suitable. |
