The　coupling　effect　of　consolidation　caused　by　the　waste　and　the　cover,　and　the　solute　transport　has　been　widely　studied　in　the　field　of　environmental　civil　engineering.　Based　on　Biot　consolidation　theory　and　solute　transport　theory,　a　three-dimensional　coupled　model　of　consolidation　and　solute　transport　is　thus　developed　and　in　the　modeltheporosity　is　thecoupled　parameter　and　consolidation　equations　is　linked　with　transport　equations.　The　influence　of　consolidation　on　solute　transport　parameters　is　taken　into　consideration　as　well..　Then,　the　3D　model　coupling　the　consolidation　and　solute　transport　is　establishedusing　the　finite　elementsoftware　COMSOL　Multiphysics.　The　numerical　results　show　that　consolidation　deformation　retards　the　transport　process　of　solute　leading　to　decrease　in　contaminant　plume　and　the　transport　depth　in　vertical　direction　and　has　a　strong　and　long-term　influence　on　the　transport　of　soluteThe　transport　distance　decreasing　rate　increased　over　time　and　reache27.75%　in　20　years;　the　transport　distance　in　the　horizontal　direction　of　contaminant　concentration　increases　with　the　increasing　of　lateral　hydraulic　gradient.　©,　2015,　Tumu　Jianzhu　yu　Huanjing　Gongcheng/Journal　of　Civil,　Architectural　and　Environmental　Engineering.　All　right　reserved.
