【 摘 要 】

The vacuum preloading method is a useful and common method in treating soft soil foundation. Lots of pore water is discharged and the foundation occur large deformation in vacuum preloading procedure. The large deformation may affect the stability of the nearby foundation, leading to cracking and differential settlement. This paper analysed the influence of vacuum preloading process on the nearby foundation with numerical simulation method based on an engineering case. The vertical and lateral displacement was calculated and the effect of implement vacuum preloading on nearby foundation was evaluated.
