Abstract: Considering the influence of lateral deformation of subgrade, bilinear settlement prediction model was advised to adopt. This model includes time series, linear regression and bilinear items. In order to study the time-dependent characteristics of parameters in the model, settlement prediction fell into parameters prediction and settlement prediction based on the former one. Multi-layer recursive method was adopted to calculate time-dependent parameters, whose tendency of movement was further analyzed. Prediction of settlement was obtained after calculating prediction values of parameters. Case study demonstrates that the bilinear dynamic prediction model is worth applying widely for well showing settlement characteristics of subgrade and having a higher precision.

Key words: lateral deformation, bilinear model, time-dependent parameter, multi-layer recursive
