Finite Element Program FEECON for Undrained Deformation Analyses of Granular Embankments on Soft Clay Foundations.

摘要

A finite element analysis of embankment construction (FEECON) was developed to enable the engineer to rationally analyze the stresses,pore pressures and undrained shear deformations caused by rapid construction of granular embankments in a series of lifts placed on soft clay foundation soil. Additional loading commands are available in FEECON to enable the analysis of other types of engineering problems,such as excavation. A choice of nonlinear,isotropic,elastic stress-strain deformation models of the soil materials is available to represent the undrained or drained shear behavior of soils. To demonstrate the applicability of the FEECON program,the second stage construction of the Fore River Test Section in South Portland,Maine,was analyzed. This analysis can be used as a basis for shear stability analysis and as a yard stick against which to compare field observations of pore pressures and displacements. (Author)
