Recent Developments in the Vacuum Preloading Technique in China

A series of studies have confirmed that vacuum preloading can effectively accelerate the consolidation process soft soil. In recent years, further improvement in efficiency this method is still continuing goal scholars. This paper reviews improvements techniques as well their practical applications China. The advantages and disadvantages each are discussed. It found replacing or eliminating one more components system, such sand-free, membrane-free, horizontal drain, multiple-step, air booster methods, achieved similar soil effects to those traditional method. Vacuum combined with other methods could improve lower average water content higher shear strength.
