In　order　to　analyze　the　uplift　bearing　capacity　of　transmission　tower　foundation　in　the　geosythetic-reinforced　aeolian　sand,　a　series　of　simplified　indoor　modeling　tests　are　carried　out.　A　simplified　reduced-scale　foundation　made　according　to　the　prototype　and　the　uplift　bearing　capacity　of　transmission　tower　foundation　in　geosynthetic-reinforced　aeolian　sand　is　studied.　Three　kinds　of　reinforcement　materials　are　embedded　in　the　sand　according　to　five　ways　of　layout　spacing.　A　total　of　15　reinforcement　schemes　are　tested.　The　results　show　that　ultimate　uplift　bearing　capacity　of　transmission　tower　foundation　can　be　significantly　improved　by　the　reinforcement　treatment　of　geotechnical　materials　in　the　aeolian　sand.　The　type　and　spacing　of　reinforced　materials　also　have　a　significant　influence　on　the　uplift　bearing　capacity　of　the　foundation　model　in　reinforced　aeolian　sand,　and　the　effect　of　reinforcement　works　until　the　end　of　the　loading　process.　The　comprehensive　effect　is　evaluated　by　the　ratio　of　bearing　capacity　improvement　and　the　total　layer　of　reinforced　materials.　Based　on　the　above　results,　the　bearing　mechanism　of　transmission　tower　foundation　in　geosynthetic-reinforced　aeolian　sand　is　elaborated　and　analyzed　in　detail.
