Deformation characteristics of high-fill temporary storage yard foundation on complex soft soil

Based on a large-scale high-fill temporary storage yard project on a complex soft soil foundation in a coastal area, the consolidation and deformation characteristics of soft soil foundation under high-fill load were studied by conducting in-situ monitoring and finite element analysis of pore water pressure and deformation of soft soil foundation under the condition of adding drainage plates. The results indicate that during the high-filling process, the overall stability and deformation of the site meet the design control requirements; under the action of large-area high-fill pile load, the vertical and lateral deformations of the foundation soil are mainly concentrated within a depth range of 6.0 meters below the surface; the drainage plate has a significant dissipation effect on the excess pore water pressure, which can effectively reduce the lateral soil pressure and deformation of the foundation, thereby reducing the disturbance effect on the surrounding environment. Compared with the predicted results of theoretical calculation models, the measured deformation of foundation soil is only more significant within a certain depth range. The research results can provide a reference for similar projects.
