真空排水预压法与堆载预压法相比具有加载快、无需堆载材料、不会失稳等优势,适用于加固软土特别是含水量较高的超软土地基。真空-堆载联合预压法的应用也越来越多。经过国内外十几年的探索,真空排水预压法日趋成熟,已经成为大面积应用的加固软土地基的行之有效的方法之一。

Compared with heaped preloading method, vacuum drainage preloading method has such advan- tages such as load speed, dispensing with loading material, no instability, etc. It is suitable for strengthening soft soil, especially the super soil foundation which has high content of water. The application of vacuum- heaped preloading is more and more. Through more than 10 years＇ exploration at home and abroad, vacuum drainage preloading method has increasingly matured and become one of the effective methods for strengthening soft soil foundation which is applied widely.
