| Abstract: | On the basis of the difference between the settlements of abutment and embankment on highway after running some days, this paper sets up the models of bump at bridge-head to analyze the mechanics character of the bump phenomenon. Combined with engineering practice, parameters of rigid-flexibility transition design of abutment back are provided also. |
