Abstract:

The stability of lining structure is influenced by over-excavation and under-excavation of the surrounding rock of tunnel. It has great significance for understanding the surrounding rock stress and ensuring construction safety to  research the law of over-excavation and under-excavation of the surrounding rock of tunnel. Based on the multi-resolution analysis of wavelet analysis and the statistical self-similarity on over-excavation and under-excavation of the surrounding rock of tunnel section profile, the fractal dimensions of 47 tunnel sections profile have been calculated by the wavelet analysis. There is a linear relationship between fractal dimension an RMR and Q rock mass classification. With the increase of RMR and lnQ values, the fractal dimension of tunnel section profile is decreased. Multiple correlations among fractal dimension of section profile, surrounding rock quality of tunnel, the over-excavation and under-excavation percentage are researched. A foundation to evaluate the stability of tunnel surrounding rock mass was established.

Key words: wavelet analysis, tunnel surrounding rock outline, fractal, rock quality, stability, tunnel
