Abstract

Abstract:

A soft clay consolidation project by using vacuum-surcharge preloading method was conducted in Zhuhai about two year ago, and finite element numerical analysis under two-dimensional plane strain condition, in which modified Cam model and soft clay permeating characteristics are considered, is finished in details for the project, with corresponding calculating results such as soft clay vertical settlement, horizontal displacement, and pore water pressure, et al. beengiven and compared with the project measuring results. Based on the calculation results, the vacuum-surcharge preloading method for the soft clay has a better consolidation effect in practice because of its effective consolidation mechanism.

Key words: vacuum-surcharge preloading, modified Cam model, numerical analysis, consolidation mechanism
