Abstract: The anchor solid bucking mode of layered roof is researched systematically at the basis of theoretical analysis and numerical simulation experiment. To be specific, in the research process, the main influence factors of the buckling mode of layered roof are grouped, the characteristics of the stress and displacement is obtained based on the UDEC numerical simulation software.
