| 摘 要： | 结合真空预压处理人工湖海相淤泥地基的工程实例,通过对真空预压卸载后地基试验区的回弹变形观测,得出结论:真空预压卸栽后地基发生1～2cm的回弹变形,回弹率为1%-2%,变形约在十天后稳定下来.对真空预压卸载后地基的回弹变形观测,能够更好地掌握其卸载后土体回弹规律,进一步评价真空预压的加固效果.

| Abstract: | 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 reinf... |
