WANG Zhi-liang, SONG Mao-tian, YIN Zong-ze. Analyses of parameters sensitivity of Duncan-Chang model in settlement calculation of embankment[J]. 2004, 25(7期 刊出日).DOI:
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.
