摘要
Compared with routine vacuum preloading method for consolidation of soft soil for the present combined with the vacuum tube network, horizontal sand blanket and prefabricated vertical drains, straight-line vacuum preloading method was improved and was innovated in design to save sand sources and funding. It has been achieved to increase efficiency, improve quality, reduce costs and shorten construction time. Both of the two vacuum preloading methods were analyzed contrastively on the field test of obtained monitoring and detection of areas of data. Straight-line vacuum preloading method was significantly improved energy efficiency. Not only did it shorten the pre-press time, but saved the material of the medium-coarse sand and reduced the project cost.
