| Abstract: | In this paper, a coupled spatial analysis model of shallow tunnels pre reinforced with surface mortar bolts is developed using 3D bolt element and a coupling program of spatial elastic plastic finite element, infinite element and bolt element is compiled. Some significant conclusions for guiding engineering design and construction are given with computing a related engineering example. |
