Bridge Transition Roadbed Disease Characteristics And Treatment Measures

At present, although all the methods for prevent jump disease at bridge abutment have some the effect, but can not radical cure the disease at all. And in our county that have affected the normal carry of highway, therefore looking for some effective measures are imperative under the situation.The paper through investigated about transition section between bridge abutment and embankment in Shaanxi,Sichuan ,Yunnan and Gansu, summing up the destroy mode are roadbed slippage with whole, forming step between roadbed and bridge abutment, road surface depressed , slab rupture, difference gradient between roadbed and slab, difference subside and crack in roadbed on end of slab. Analyzed the destroy mechanism with correlation theories and MARC numerical simulation.Giving some treatment method about ground base, sub grade, road surface and all of them, all the work I do have some reference worthiness for the jump disease at bridge abutment on highway.
