Two-Dimensional Finite Element Analysis of Vacuum Preloading of Soft Soil Foundation with Sand Layer
When vacuum preloading is applied to treat soft soil foundations with sandy layers,quantitative analy-sis of the influence of the sandy layers on foundation deformation is constrained by the limitations of on-site ex-perimental conditions.Taking a coastal engineering project in Wenzhou as an example,finite element modeling was utilized to numerically simulate the vacuum preloading reinforcement process for soil samples exhibiting sig-nificant differences in physical and mechanical properties,such as fine sand with silt and silt.The simulation analysis results were compared with on-site measured data,elucidating the facilitating role of sandy layers in promoting drainage in soft soil foundations,it revealed that under the condition of constant sand layer thickness,the deeper the burial depth of the sandy layer,the greater the stratified settlement and lateral displacement of the soft soil foundation.The study validated the rationality of the finite element model,providing valuable insights for the application of vacuum preloading technology similar geological conditions.
