摘要/Abstract

摘要： 从分形几何角度分析，隧道围岩超欠挖具有自相似性，对于一定洞径的隧道，隧道围岩超欠挖曲线分形维数是岩体结构和洞轴线的函数。对于主要发育一组陡倾节理的情况研究表明,隧道围岩超欠挖曲线分形维数与节理间距呈双对数线性关系，与节理走向和洞轴线的夹角呈双对数线性关系，并建立了它们之间的多元关系。

关键词: 公路隧道, 超欠挖, 分形维数, 岩体节理, 洞轴线

Abstract: Applying the fractal geometry, it have been indicated that the overbreak-underbreak curve of tunnel has a self-similarity, and the fractal dimension of the overbreak-underbreak of tunnel is the function of structure of rock mass and the tunnel axes. On the basis of it, to a set of steep joints, it has the double logarithm linear relation between overbreak-underbreak and joints spacing, and it has the double logarithm linear relation between overbreak-underbreak and angle between joints and tunnel axes, too. Finally, the multi-relation among them is built up.

Key words: highway tunnel, overbreak-underbreak, fractal dimension, rock mass joints, tunnel axes
