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.
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。
It is a very difficult problem of overbreak in tunnel excavation.
超欠挖一直是隧道开挖中遇到的一大难题,文章在对金丽温高速木西岙连拱隧道超欠挖现场调查的基础上绘制出开挖断面线及平均开挖断面线,应用在评价岩体结构面几何形态时普遍使用的粗糙度方法对断面线进行评价,以分析开挖断面上不同部位超欠挖的差异性。
On the base of investigation of overbreak in Jinliwen expressway doubled arch tunnels,the projection map of overbreak blocks in excavating section is drawn in this paper.
