Abstract

In order to explore the difference between vacuum preloading without sand cushion and gravel pile, sand pile, and surcharge combined sand pile technology on the reinforcement effect of soft soil foundation, comparative tests were carried out in four areas at the test site. The test results show that the vacuum preloading technology without sand cushion has good drainage performance. After using this technology, a hard-shell layer with high strength can be formed on the surface of the foundation, and the foundation treatment effect of the combined sand well technology is close to that of the vacuum preloading method. The study also found that the reinforcement uniformity of the sand-free cushion vacuum preloading method is weak, and the settlement is uneven during the process. The results of this study provide theoretical support for the comparison and selection of design schemes for soft soil foundation reinforcement.
