Abstract: Mechanism of settlement of ramp loading roadbed on soft ground is analyzed; and proof of settlement－time curve appearing S-shape is conducted directly based on consolidation degree of one-dimension soil consolidation theory. Mathematical analyses of Gompertz, logistic, Weibull growth model that appearing S-shape are conducted. Although Gompertz, logistic growth models are adopted extensively to predict settlement of ramp loading roadbed, they have deficiencies such as: (1)neglecting loading velocity; (2)neglecting construction art; (3) relative constant ratio of settlement at inflection point to ultimate settlement. Good usability of Weibull growth model is pointed out. Finally, suggests on prediction of soft roadbed settlement are proposed.

Key words: settlement of roadbed, consolidation degree, S-shape curve, ultimate settlement, inflection point
