An Overview of the New Method of Vacuum Preloading for Ultra-Soft Soil Foundation Engineering

The vacuum preloading method has achieved good results in the foundation treatment of similar ultra-soft sedimentary soils, and been gradually recognized adopted by industry. This paper summarizes introduces different types new methods at home abroad, analyzes characteristics research progress methods. show that although continuously innovated reformed practice, defects itself cannot be completely avoided, especially soil with ultra-high water content high floating mud. Many problems emerged process dealing it, it is urgent for scholars to continue development.
