| In the Advanced Highway disease in Bumping at bridgehead is a common problem. Paper first Bumping at bridgehead phenomena and the causes of uneven settlement of the bridgehead and hazard were also discussed, proposed several methods to solve differential settlement, focused on analysis of project characteristics and geogrid reinforcement mechanisms. Experimental control through indoor grille and the interface between the role of the effect of soil, As well as the packing density in different, under different moisture conditions change in the value of packing c,?, identify variation, so by the relevant simulation parameters.The use of geogrid reinforced embankment of bridge is a solution to the phenomenon of new technologies Bump, the effect of engineering practice is clear, but the theory is still defective. This article as long as the actual situation in accordance with Six Potential Highway, combination of engineering practice, establish finite element model, Through the finite element model that focused on analysis of different embankment under the program of post-construction settlement rules geogrid stress and strain distribution, then to determine the optimal design. By numerical calculation and theoretical analysis, demonstrated that treatment geogrid reinforced embankment Bridge Transitional Section, reduce the differential settlement can be a good, to control the purpose of the Bump.In this paper, six potential highway based on a typical Bump, combination of engineering practice. Theoretically clarify the selection of suitable layout spacing, reinforcement layer, reinforcement of the embankment in order to obtain better results。The better use earthwork grill reinforcement technology realizes the abutment and Hard and soft two kind of foundations between the bridge head embankment's could pass smoothly, to control the purpose of the Bump. Provides the theory basis for the actual project's technical choice, provides the reference for the actual project.
