| Abstract: | Considering the effects of filling earth in abutments on the bridge abutments in the light of the Conlomb earth pressure theory,the authors discuss;the compression stress situations of different huge Ushaped abutments with a super FEM(finite element method)programme.The results indicate that the filling of earth has obvious effects on the abutments,which must be taken into account in the process of design.Put forth are some related design suggestions for the huge U-shaped abutments. |
