  Stability Analysis of Tunnels in Upper Soft and Lower Hard Composite Strata

  Abstract: During tunnelling, the stratum of the tunnel faces appear two or more different physical and mechanical characteristics. In this paper, the stability of tunnel construction in upper soft and lower hard typical composite strata is studied. The influence of thickness-span ratio, height-span ratio, stratum stratification ratio, stratum physical and mechanical parameters, and stratification dip...
