摘要

Based on Biot’s linearized quasi-static elasticity theory ofrnfluid-infiltrated porous materials, the constituentrncompressibilities of fluid and solid are taken into fullyrnaccount on the mathematical modelling. The study isrnfocused on the analytic solutions of transientrnconsolidation due to a point sink. Using Laplace-Hankelrnintegral transforms to solve the presented model, closedformrnsolutions of horizontal displacement, settlement andrnexcess pore fluid pressure of the strata are derived. Therncompressibility of solid skeleton and pore fluid arernimportant on transient consolidation deformation process.rnHowever, the long-term consolidation behaviors due torngroundwater withdrawal are not directly dependent on therncompressibility of poroelastic constituents of the saturatedrnaquifer.
