英文摘要	In order to determine the static stability and optimal construction method for the large-section loess tunnel, based on ANAYS finite element software, it analyzed the stability under static force by three common construction methods (bench method, double side-drift method and CD method). The safety coefficients of shearing strength under 3 construction methods are obtained through continuously reducing the cohesion strength and internal friction angle. The safety coefficients and layout of plastic zone indicate that strength reduction method is able to determine the safety coefficients of tunnel and evaluate tunnel stability and merits and demerits of tunnel construction method; double side-drift method is relatively reasonable for construction of large-section loess tunnel because of its maximum safety coefficient. ©, 2015, Editorial Office of "Modern Tunnelling Technology".
