Abstract: Simplified method of ground settlement under negative pressure is studied, which the deformation mechanism under vacuum preloading is considered. Observation of settlement for vacuum preloading engineering shows that the practical settlement is smaller than the predicted one based on the National Code of China. The settlement correction factors for vacuum preloading and vacuum combined surcharging preloading are established based on theoretical derivation. It is concluded that the scope of ground settlement correction factor ms may be 0.55 to 1.20 for vacuum preload engineering; and 0.70 to 1.30 for vacuum combined surcharge preloading with layer wise summation method .

Key words: vacuum preloading, vacuum combined surcharge preloading, layer wise summation method, settlement correction factor
