Abstract: In the process of the preloading, the foundation stability is calculated from one stage of filling height to next stage of filling height. According to the foundation stability the filling height and the loading time of the next stage could be given out. According to the results of Biot’s consolidation theory in each filling height, the foundation stability is calculated with the total stress method considering the strength increase and the effective stress method considering the over-static water pressure. Then an useful result is that the foundation stability factors calculated by the two methods are approximate equality.

Key words: preloading, foundation stability, strength increasing, over-static water pressure, total stress method, effective stress method
