摘要
用真空预压法加固某高速公路高填方路堤软土地基的现场试验结果表明 ,该法加固效果明显 ,与堆载预压法相比 ,采用真空预压法的工期短、地基土强度增长快。
The soft subgrade with high fill of an express highway is improved by vacuum preloading method, Field observation results indicate that the improving effect is evident. Compared with the preloading method, the construction time of the vacuum preloading method is short, the strength of the subgrade soil increases quickly, the settlement of the subgrade is small and the embankment is stable.
