| Abstract: | Vacuum and load preloading method is widely used for consolidation of soft soil roadbed in highways. Compared with the normal load preloading method,it can reduce the post-construction settlement, save the construction time and guarantee the stability of the roadbed. This paper explains the mechanism of the method through engineering practice and then demonstrates its good effects on the consolidation of soft soil roadbed by analyzing the monitored data. |
