Finite element analyses of building structures jointed to a loess tunnel;

Exploration of design methods of support structure in loess tunnel

Through analyzing the failure mechanism of loess tunnel,applying the idea of strength reduction finite element method,the definition of shear safety factor and tensile safety factor can be got during the stability analysis of loess tunnel.
