To　explore　the　influences　of　temperature　on　pollutant　transport,　a　coupled　model　for　contaminant　diffusion　in　soils,　osmosis　and　consolidation　considering　the　thermal　effects　is　proposed　to　reflect　the　dynamic　changes　of　physical　properties　of　soils　and　transport　properties　in　the　process　of　pollutant　transport　and　realize　the　coupling　of　diffusion,　osmosis　and　consolidation.　On　the　basis　of　verifying　the　validity　of　the　model,　the　effects　of　thermal　diffusion,　thermo-osmosis,　thermal　consolidation　and　their　combined　effect　on　pollutant　transport　are　analyzed.　The　simulated　results　show　that　the　thermal　diffusion　and　thermo-osmosis　can　accelerate　contaminant　transport,　and　with　the　increase　of　Soret　coefficient　and　thermal　permeability,　the　thermal　diffusion　and　thermo-osmosis　effects　enhance.　However,　the　thermal　consolidation　can　slow　down　the　pollutant　transport　rate,　but　with　the　increase　of　expansion　coefficient　of　soils,　the　accumulation　concentration　of　pollutant　at　the　bottom　of　clay　layer　has　little　change.　When　the　temperature　difference　is　40　K,　the　breakthrough　time　with　considering　the　combined　effects　of　thermal　diffusion,　thermo-osmosis　and　thermal　consolidation　can　be　shortened　by　53.97　years　compared　with　the　results　without　considering　the　thermal　effects.　©　2022,　Editorial　Office　of　Chinese　Journal　of　Geotechnical　Engineering.　All　right　reserved.
