Highway bridge transition section is disease -prone area, \This article from the Bump hazard analysis , analyzes of differential settlement of bridge causes, given the range of differential settlement and Treatment calculation method , and the transition section to determine the scope and Treatment of differential settlements after the amount of control were discussed . Through analysis of slab , dust for filling , lime and fly ash for fill , geogrid reinforced soil Geocell flexible approach slab , lightweight material and semi-rigid Piles Composite Foundation Treatment Treatment Measures such as common mechanism and adaptation sex , divided their scope, on this basis , common treatment measures proposed engineering solutions and give a method to determine the design parameters , but also on the characteristics of each summary. Finally, with engineering examples , the design plan of the economy, rationality and validity are discussed.
