A　transport　model　with　thermo-hydro-mechanical-chemical　coupling　in　single　solute　in　saturated　soil　was　proposed,　based　on　the　principle　of　mass　conservation　of　pore　fluid,　energy　conservation　and　mass　conservation　of　solute　considering　the　influences　of　mechanical　consolidation,　heat　consolidation　and　chemical-osmosis　consolidation　on　the　soil　structure　together.　Meanwhile,　the　adsorption　of　clay　particles,　semi-membrane　behavior,　coupled　flow　and　diffusion　were　all　included.　The　influence　of　the　temperature　on　the　solute　transport　process　was　simulated　by　software　COMSOL.　The　numerical　results　show　that　the　temperature　has　an　important　effect　on　the　concentration　distribution　of　solute　with　time　and　soil　depth,　the　thermal　diffusion　accelerates　the　solute　transport　and　the　process　of　thermos-osmosis,　and　heat　consolidation　retards　the　solute　transport.　When　the　transport　time　reaches　50　years,　the　transport　depth　of　the　solute　under　the　temperature　difference　70　K　between　upper　and　lower　boundaries　of　clay　liner　slows　down　by　87.6%　compared　with　that　without　the　temperature　difference.　The　fully　coupled　model　can　provide　a　theoretical　support　for　the　barrier　design　of　the　landfill　and　the　evaluation　of　service　life.　©　2019,　Editorial　Department　of　Journal　of　Southeast　University.　All　right　reserved.
