摘要：It is common that the foundations have under soft layer in engineering; however their failure mechanism depends on assumed condition and experience to a large extent. The paper carries out strain controlling numerical experiment for a foundation model with under soft layer based on limit analysis and fast Lagrangian numerical simulation method; the simulation result shows obvious size effect. Simulation also gets the different ultimate bearing capacities, stress-strain curves, progressive failure pattern, and the under soft layer settlements corresponding to different loading sizes. The safety factors respectively acquired by load increasing method and strength reduction method based on above numerical model are also compared, they have the same changing trend according to the loading size changing; but the value of former is smaller.
