Abstract: For the three-dimensional consolidation effect impersonal existence of roadbed and the horizontal thrust from stresses re-distribution of embankment, soil lateral deformation should not be neglected. The modification formula based on height of embankment and void ratio of roadbed for common clay and soft soil is severally given through nonlinear finite element method, which are mainly applicable to uniform or non-uniform roadbed case. It is tested that, using this method, the settlement one-dimensional calculated results can be in consideration of soil lateral displacement with engineering example. Furthermore, the modified settlement is more closed to measurement. In a way, those formulas have definite inference value in practice.

Key words: embankment, settlement, one-dimensional method, lateral deformation, nonlinear finite element method, settlement modification coefficient
