Abstract

Based on the soil-water coupled finite element analysis, the vacuum consolidation of soft reclaimed ground is investigated systematically. The engineering background, ground profiles and improvement scheme are firstly introduced in detail, which is also a preparation for the following numerical calculations. Through a series of calculations, the deformation characteristics of the deep-soft ground can be captured numerically, which is also very close to the practical engineering. The results show that 1) with the duration of the vacuum preloading, the ground of the improved area deforms like a boiler, which is in accordance to the practical engineering; 2) The decreasing rate gradually decreases as the ongoing preloading and the pore pressure keeps almost stable at the end of the vacuum preloading; 3) The influence area of the vacuum preloading can be approximately estimated through the contours.
