ABSTRACT
In national and foreign document, it is seldom mended about predicting seismic subsidence of loess ground with 2-D and 3-D Finite-Element Method (FEM). In the study, the FEM are used to predict the seismic subsidence, and the relations, among the subsidence characteristic of loess ground and the site, the foundations, the soil dynamic property, can be studied quantitatively. As a method, it can provide the theoretical laws for seismic design and seismic resistance. In the same time, loess dynamics used in earthquake engineering is developed greatly.
