In order to study the time-dependent characteristics of the parameters in the settlement prediction model, A multi-layer recursive time series model was presented. Prediction of settlement was divided into two parts: the prediction of time-dependent parameters, and the prediction of settlement based on the parameters' prediction. The parameters of the settlement time series prediction model were calculated through a recursive formula. Based on which the parameters yielded, the parameters time series prediction models were presented. By analogy, the multi-layer parameter prediction models could be developed until the parameters were time-independent. Lastly, based on the parameter predicting results, the post settlement was calculated through the time series model. The case result shows that the multi-layer recursive time series model is effective in analyzing the time-dependent characteristics of parameters, and has considerable prediction precision.
