Test study on rebound deformation of foundation after unloading by vacuum preloading

YAN Wei-feng(Henan Jinjian Construction Co.,Ltd.,Pingdingshan 467000,China)  
Combined with an engineering case of artificial lake marine silt foundation treatment by vacuum preloading method,through observing foundation rebound deformation after unloading by vacuum preloading,it shows that the foundation yields one or two centimeters rebound deformation,one or two percent rebound rate,and rebound deformation becomes stable in ten days.Through observing foundation rebound deformation after unloading by vacuum preloading,soil rebound law can be understood after unloading,and the reinforcement effect can be also evaluated.
