Field test study on deep soft soil reinforcement by vacuum preloading without sand cushion
To evaluate the difference in reinforcement effect between vacuum preloading without sand cushion and conventional vacuum preloading for deep soft foundation, field comparative tests are carried out. The results show that the surface settlement during vacuum preloading without sand cushion is about 17% higher than that of conventional vacuum preloading, and the strength growth after vacuum preloading without sand cushion is about 26% higher than that of conventional vacuum preloading. The study also reveals that the reinforcement uniformity of the sand-free cushion method is weaker than that of the conventional vacuum preloading method. The research results will provide data support for the design and scheme comparison of soft foundation reinforcement by drainage consolidation method in the future.
