摘要
隧道在不同岩体中开挖后,都有着不同程度的变形沉降。对于硬质岩体隧道沉降变形有着一定的规律,而软岩隧道一般沉降变形比较复杂。本文以纸坊隧道为例,基于Koch分形理论,对隧道DK201+865处进行二维平面分析研究。通过现场沉降检测数据与分形计算结果对比,来证明Koch分形扩展理论适合于本隧道的沉降计算。
Tunnel in different rock after excavation, always has a different degree of deformation and settlement. For hard rock tunnel settlement deformation, it has a certain regularity, but soft rock tunnel settlement deformation is more complicated. In this paper, Zhi Fang tunnel used as an example, based on the Koch fractal theory, DK201 ＋ 865 of tunnel is analyzed and researched. Through compared field settlement detection data and fractal calculation results, to prove that Koch fractal theory can be applied in the settlement calculation of the tunnel.
