Case Study: Ground Improvement of Yangtze River Floodplain

Dec 12,  · In this paper, a case study on soft clay treatment with the vacuum preloading method (VPM) and combined vacuum and surcharge preloading method (CV-SPM) is introduced and discussed. Negative pore-water pressure was induced by vacuum pressure in the VPM, which led to the seepage of water and consolidation of soils.

Ground Improvement Techniques for Liquefaction

Many of the case studies available in the literature do not cover all aspects of the project, rather they emphasize one or two aspects. For example, a case study may focus on ground improvement methodology, giving little information on seismic evaluation. In some cases, even key information on ground improvement methodology is lacking.
