摘要：Taking integrated pipe gallery of Tongzhou City Sub-center in Beijing as studied project, the research on the formulation of solidified soil and its preparation process were carried out for the silty clay and sandy soil samples on the site. The parameters were analyzed by finite element software simulation, which in results show that the ready-mixed fluidized solidified soil is characterized by high strength, self-compacting performance, impermeability, water stability, construction performance, and economic performance. It is in advanced compared with the traditional backfill materials. The application of solidified soil technology needs to be developed to adapt special equipment. After 7 days of placing the concrete structure, in view of factors of construction quality and construction period, the concrete structure is selected to be demolished for backfilling of the pre-mixed fluidized solidified soil, with single backfilling 0.5 meters and 1 meter respectively. The impermeability and water stability of the ready-mixed fluidized solidified soil are qualified. but the resistance to freezing and thawing is unacceptable. The mixed fluidized solidified soil should be backfilled in the area below the frozen soil layer.
