Research on the Anchorage-Reinforced Technology in the Highway Subgrade Widening Projects
The new anchorage-reinforced technology in the highway subgrade widening project is put forward in order to realize the effective joining between the new and the existing subgrade. The anchoring mechanism of anchoring bar and the function mechanism of geogrids in the joining between the new and the existing subgrade are analyzed in this paper. The design method of anchorage-reinforced composite structure is studied. Based on the finite element method (FEM), the characteristics of the ground settlement and horizontal displacement, sungrade surface settlement and the geogrids stress are researched according to the three subgrade widening schemes; that is, excavation step only, excavation step + geogrid reinforcement, and excavation step + geogrid reinforcement + anchor bolt. These study results can be used as a reference for future studies and designs of highway subgrade widening projects.
