Influence of vacuum preloading on surrounding soil ground and structures

Abstract

Combined with a project analysis, the numerical modeling method was used to simulate the influence of vacuum preloading on the surrounding soil ground and structures. The results show that vacuum preloading has little effect on the soil ground when the soil ground is reinforced by vacuum preloading method. When the adjacent soil ground is reinforced by the cement mixing piles or the steel pipe piles, the soil ground will have large uneven settlement, which will affect the safety of the upper structures. The calculation results are consistent with the on-site observation, which can provide experience and references for the application of vacuum preloading method to reinforce soft soil ground.
