| Abstract: | Consolidation and settlement characteristics of soft soil are major concerns during the design and construction of road projects in deep soft soil areas.The deformation and stress changes of soft foundation are analyzed under preloading in a shoal hydraulic fill area of Baoshan Iron & Steel Co.,Ltd.in Shanghai,and the geotechnical finite element soft PLAXIS is used to simulate the layered buried progress of soft soil foundation,the change of ground deformation and stress are analyzed so the law of consolidation and settlement development is obtained,and it provides the basis for the design and construction control. |

| Keywords: | soft soil foundation hydraulic fill settlement consolidation finite element method |
