Experiment Research on Deeply Soft Foundation Treatment by Plastic Drainage Plate Preloading Method

The method of plastic drainage plate preloading is taken to treat deeply soft foundation.Lots of aspects are analyzed to evaluate the effect of treatment,including layering settlement,pore water pressure,horizontal deformation,in-situ test results of CPT and the laboratory soil test.The results demonstrate that method of plastic drainage plate preloading is suit to treat deeply soft foundation.Moreover,this treatment method is entirely satisfied with the requirement of design.
