Finite element method is a familiar method in settlement calculation of embankment
and the authenticity of soil model parameters is the guarantee of higher accurate results. Firstly
the analyses aimed at influencing degree of Duncan-Chang model parameters to settlement are done; and the five parameters with larger sensitivity are found; Then with artificial neural network technology
a thought of two model parameters modification (K
G) is brought forward combined with measured settlements. It shows that this thought is reasonable and the calculational results with modified parameters are more precise. In a way
