Bump Disease Prevention And Treatment Research

Associating different field project, this paper adopts different embankment fillers and different treatment methods of foundation to prevent the jump disease at bridge abutment, and the actual data show the treatment effect is apparent. Adopt half-integral abutment approach slab to adjust the mechanical performance of bridge abutment, finite element analysis results show the long and large slope abutment approach slab in favor of its stableness. Through conservation of energy, this paper establishes wheeling load calculating formula of bridge abutment, and the formula is applicable to the calculating and design of bridge abutment, in addition , establish the repair criterion of jump disease ,and based on the criterion, gave the slap length calculating formula.
