摘要:

AbstractA general semi‐analytical method is presented for the analysis of seabed response under wave action during a storm. The seabed is idealized as a poro‐elastic medium filled with a single compressible fluid with anisotropic flow. The coupled process of fluid flow and deformation of soil skeleton is formulated in the framework of Biot's theory.The analysis for the response of homogeneous seabed of finite thickness under a plane progressive wave is developed first, followed by an extension for the case of a layered seabed. A generalization for three‐dimensional response of seabed is also developed for a general wave field which provides the analyses for seabed response under short‐crested or standing waves in the vicinity of a structure. Some numerical examples illustrating the proposed analyses are also pr

摘要:

AbstractA numerical method is developed in this paper for the analysis of the behaviour of a raft resting on a consolidating soil. The response of the raft under an applied loading is determined using the finite layer method for the soil and the finite element method for the raft. By considering deflection compatibility on the contact surface, the distribution of contact pressure is computed at various time steps. The settlement and bending moment in the raft is then evaluated by applying the calculated contact pressure back to the raft. It is shown that, in some cases, the maximum moment in the raft occurs during consolidation and that checking the final moment in the raft by use of elastic theory may not be sufficient.

摘要:

AbstractThe paper describes the basic ideas and the main features of a new class of constitutive laws, in the framework of incrementally non‐linear constitutive equations. CLoE is a generic name for that new class of laws, with reference to consistency at the limit surface, and explicit localization analysis. A top–down analysis of the model is presented, and illustrated by examp
