Abstract: The analyses of sensitivity have been considered to be one main method in the solution to identification of many parameters in civil engineering. At present, during the course of analysis and calculation in underground engineering, Duncan-Chang model is an ideal one. By a lot of nonlinear finite element method calculation, the main parameters, which have much larger influence on the calculated accuracy of embankment settlement, are found out; and then the qualitative relations between every parameter and embankment settlement are also given, and that can be the basis of simple disposal for back analysis of the model parameters in practical engineering.

Key words: embankment, settlement, Duncan-Chang model, sensitivity analysis
