Soft soil improvement analysis method of Light-weighted Foam Soils

摘要

bubbles mixed lightweight soil soft ground improved analytical methods for initiating. The bubbles mixed lightweight soil improvement soft ground downwind soil analysis methods, clay, sand and fill the soft soil layer setting step that sets the soft soil layers sequentially stacked virtual (S110); The SCP process a portion of the soft clay subjected to load the embankment of the ground floor, mixed soil lightweight process, improving soft ground improved by applying each step of the DCM method (S120); Three-dimensional figures to analyze the deformation behavior of soft soil layer improved according to the above method due to the embankment load was applied to three-dimensional numerical analysis step (S130); And SCP method a portion of the clay layer, light mixed soil method, a comparison step (S140) for comparing the settlement generation state from the DCM method to fill load of the soft soil layer improved by applying respectively, and the three-dimensional numerical analysis is by using a finite element analysis model, characterized by applying the excessive generation of pore water pressure and spreading and compacting phenomena in the light mixed soil due to the surcharge load. ;
