Lime　treatment　is　an　economical　and　useful　soil　improvement　method.　However,　lime-treated　soils　in　site　always　present　a　serious　degradation　in　strength,　since　they　are　exposed　to　the　long-term　changes　in　climate　and　environment.　Water　retention　curve　is　essential　to　study　the　pore　water　movement　inside　soils　and　their　hydro-mechanical　behavior.　This　paper　investigates　the　influences　of　temperature　and　curing　time　on　the　water　retention　curve　of　lime-treated　soil.　In　this　test,　untreated　samples　and　lime-treated　samples(28,　90　d)were　statically　compacted.　The　water　retention　curves　of　untreated　and　lime-treated　samples　were　measured　at　different　temperatures　(0~40　℃).　The　results　indicate　that　the　water　retention　capacity　of　loess　is　effected　by　lime　treatment,　curing　time　and　temperature　changes.　The　effect　decreased　with　the　moisture　content　dropping.　The　temperature　effect　gradually　weakens　with　the　temperature　increases.　Besides,　the　VG　model　was　applied　to　model　the　water　retention　curve　of　loess.　And　the　effects　of　temperature　and　curing　time　on　the　parameters　of　a,　n,　θs,　θr　are　analyzed.　The　research　results　can　provide　useful　information　for　engineering　construction.　©　2020,　Editorial　Department　of　JCEE.　All　right　reserved.
