Abstract

Since the existing numerical simulation calculation methods of vacuum stacking combined with precompression soft base treatment are mostly applied according to the vacuum degree unchanged or linearly decreasing along the depth, in fact, with the passage of time, due to the cracking of the surrounding soil, the vacuum degree will also show an overall downward trend over time. In this paper, the MIDAS GTS finite element software is used to consider the influence of well resistance effect and time effect on vacuum, and the numerical simulation and comparison study of vacuum combined with stacked soft base treatment are carried out, and the results show that the loss of vacuum degree due to depth and time will have a certain impact on the final soft base treatment effect.
