College of Civil Engineering and Urban Construction，Jiujiang University，Jiujiang 332005
Abstract A novel model based on empirical mode decomposition and gene expression programming for landslide deformation prediction is presented.From the perspective of timefrequency analysis，firstly，deformation time series was decomposed into different frequency component through the empirical mode decomposition.Then，a program is constructed for the approximate series and detail series using gene expression to get prediction results.Finally，the results were composed.Experimental result indicates that the prediction presision is higher than GM(1，1)，AR and LSSVM.
Key words ：
empirical mode decomposition
gene expression programming
landslide deformation prediction
model evaluation index
time-frequency analysis
