Bridgehead Bump structures Abutment uneven subsidence caused by the expressway to the one of the \Less paper combines ( temple ) Rockwell ( yang ) highway project Abutment Treatment , access to a large number of domestic and international literature on the basis of the analysis of the dangers of Bump ; by Bridgehead investigation , analysis of the bridge jump the reason of the car , while the longitudinal slope change , dislocation and depression , cross slope change is uneven settlement of the three forms ; analysis Bump mechanism in the form of differential settlement ; deformation of foundation settlement and embankment itself deformation compression Abutment settlement two constituent part composed of two parts , both deformation settlement calculation method is derived to explore the degree of compaction , filling height and the relationship of the settlement ; comfort and safety of the principle , proposed the uneven subsidence control standards . On this basis , from the foundation Treatment abutment back embankment Pavement Treatment and drainage measures studied Bump Integrated Control Technology Replacement Method , compaction, cement and fly ash gravel pile and drainage solid knot Ground Treatment method ; the geogrid , dynamic compaction method and two gray mixture backfilling Abutment Treatment method ; setting bridgehead tray and transitional road abutment back pavement Treatment methods; , and back drainage improvement measures .
