| 摘 要： | 峨嵋山柱状节理玄武岩是西南地区分布的主要岩类。柱状节理玄武岩的原生建造、构造作用和风化卸荷对岩体结构和工程性状有较大的影响。节理裂隙影响岩体结构并劣化岩体完整性,分维数D能客观地表现岩体完整性特征,因而分析讨论柱状节理岩体节理面的分形特征,可以深层次的反映柱状节理岩体的工程地质特点。

| Abstract: | The Emeishan basalt with columnar joints is widely exposed in southwest China.The development of columnar joints exerts a tremendous influence on engineering property of basalt rock mass.Engineering behavior of the basalt rock mass may be characterized by fractal dimension(D),thus,study of the fractal characteristics of structural plane of the basalt can obtain the engineering-geological characteristics of the basalt rock mass. |
