摘要
岩体中结构面的存在往往会对岩体质量造成显著影响。笔者剖析了传统岩体质量指标的不足,以白云鄂博铁矿主矿边坡岩体为例,在工程地质测绘的基础上,利用蒙特卡洛(Monte Carlo)法仿真出三维岩体结构网络图,从多重分形几何的角度出发,计算和绘制出其表征岩体结构分布和复杂性的多重分形谱,对岩体质量作出定性评价和定量分析,并且进行了岩体质量的多重分形分类。
The existence of structural surface in rock mass often has notable influence on rock mass quality. This paper analyzes the evident shortcoming of the traditional rock mass quality index; and based on the project geological survey of main mine side slope rock mass of Baiyunebo iron mine, the rock mass structural network graphics are drawn by using the Monte Carlo method and the multifractal spectrum of rock mass structural distribution and complexity is calculated and drawn according to the standpoint of multifractal geometry. The qualitative evaluation and quantitative analysis for rock mass are made. The rock mass quality classification is also made based on multifractal spectrum.
