Application of vacuum preloading method in consolidating soft soil foundation

Based on the field data of soft foundation reinforcement, the variation laws of soil surface settlements, stratified settlements, horizontal displacements, pore water pressures and vacuum degrees are analyzed by use of the vacuum preloading technique, the treatment effect of this method is verified. The design of the test area is carried out, and the time of the combination of vacuum and surcharge is discussed. The results may provide reference for similar projects.
