Abstract

For the research of vacuum pre-compression is still lagging behind the engineering problems, based on the Shenzhen Marine Emerging Industry Base Soft Foundation Treatment Project, this paper adopts the finite element soft foundation to establish the vacuum pre-compression modeling method, and considers the effect of laying different lengths of drainage boards on the effect of vacuum pre-compression. The vacuum in the consolidation process with time and depth of the complex attenuation, carried out the laying of different lengths of drainage boards on the effect of vacuum pre-compression, the results show that: (1) vacuum pre-compression vertical settlement according to the three different conditions from large to small, in order of alternating lengths of short and long, long drainage boards and short drainage boards. (2) The size of the horizontal displacement is affected by the length of the drainage board, and the longer the drainage board, the larger the horizontal displacement; in addition, the different physical parameters of the soil layer have a significant effect on the horizontal displacement. (3) The consolidation effect of laying drainboards with alternating lengths is slightly better than that of laying all long drainboards, and it saves materials.
