中文摘要：
岩体内裂隙在不同方向上的间距不仅可以反映岩体的非均质性、各向异性,而且可以反映裂隙的空间分布特征,因此,在随机数学的基础上提出了一种基于裂隙间距来划分岩体结构统计均质区的方法.通过逐步改变样本空间范围的方法对松塔水电站右岸某平硐的岩体结构统计均质区进行划分,证明了岩体结构统计均质区存在空间效应.最后将考虑空间效应的划分结果与岩体声波测试曲线进行对比,证明了划分结果与现场实际是吻合的.
英文摘要：
Fracture spacing in different directions can not only reflect heterogeneity and anisotropy of rock mass, but also can reflect the spatial distribution characteristics of fracture, therefore, a method that demarcate structural homogeneity according to fracture spacing is proposed on the basis of random mathematics. The method is successfully applied to the analysis of structural homogeneity in an adit of Songta hydro-power station. It is proved that there exists the spatial effect when dividing the structural homogeneity by changing the space of the compared samples. Compared with the acoustic test curve of rock mass, it is shown that the division of structural homogeneity with the spatial effect considered is consistent with the on-site situation.
