| Abstract: | The main method to treat the soft foundation of marine deposits along the coast is drainage consolidation.It is developing with the increasing need of the engineering projects.The primary principle,reinforced characteristics and effect of the vacuum and embankment preloading are discussed synthetically in this paper.This method using the principle of the effect of vacuum preloading and embankment preloading can be superimposed,so it can get bigger preloading load and better consolidation effect than vacuum preloading.At the same time its effect and foreground are analyzed in some engineering cases in this paper. |
