Abstract: In the light of that the increase of bearing capacity of a single cemcnt soil pile is obvious as time goes on, an unequal time series grey forecasting model of GM(1,1) is established according to the grey theory; and a single cement soil pile’s bearing capacity is well forecasted by the established model. Through the comparative analysis of the observed data and forecasting date, the time effect law and change tendency of single pile’s bearing capacity are made clear. Finally, the suitable time is suggested to loading test of the cement soil pile.

Key words: bearing capacity, time effect, GM(1,1)model, forecasting
