To effectively solve the problem of soft-clay ground settlement and lateral deformation during the stage construction, making sure roadbed quality and safety and stability, combining with the project instance of soft-clay ground during the stage construction for the Hebei Province Coastal Expressway, the numerical computation for soft-clay ground deformation properties under stage construction loading has been done using the finite element method. And the evolution mechanism of stability invalidation for the soft-clay ground has been researched from three directions of the soil relative shear strength, displacement increments and plastic zone development. The research has theoretical significance and model function on roadbed stability analysis and information construction.
