| 摘 要： | 1 Introduction a Shallow foundation is widely used in civil engineering. Its bearing capacity and settlement are important research subjects in soil mechanics and foundation engineering 1]. Because of the complexity of soil engineering properties, the subject is still under development and improvement. Now the rigid-plastic limit equilibrium method based on the classic plasticity theory is widely used in the engineering practice in China. But soil is not rigid- plastic actually. Hence, the …

| Abstract: | Finite and infinite coupled element method was used to analyze the strength and deformation in layered soil foundation which was under the rectangular shallow footing subjected to vertical loads. In the numerical analysis, the footing was assumed to be elastic; the soil was assumed to be elastoplastic and the Drucker-Prager constitutive model was applied to describe its mechanic behavior. Corresponding program was employed to compute six kinds of layered soil foundations constituted by different soil layers. The conclusions which are useful in the theory and practice were made according to the analysis of the computation results. |
