Low　geosynthetic-reinforced　embankments　have　a　higher　bearing　capacity.　In　addition,　the　horizontal　geosynthetics　can　prevent　embankment　from　collapsing　suddenly,　which　plays　a　warning　role.　The　design　of　geosynthetic-reinforced　platforms　based　on　the　load　transfer　mechanisms　of　low　embankment　in　karstic　regions　should　be　proposed,　for　which　the　existing　design　methods　are　not　recommended　because　of　the　complex　mechanisms.　By　analyzing　the　stress-strain　relations　of　the　platform,　the　design　considering　the　principal　stress　rotation　due　to　differential　settlements　is　improved　and　optimized　under　the　assumption　that　there　is　a　parabolic　overload　distribution　perpendicular　to　the　sheet　overlying　the　void.　The　design　method　for　the　tensile　stiffness　of　geosynthetic-reinforced　sheet　and　the　embankment　height　based　on　the　load　transfer　mechanisms　of　low　reinforced　embankment　spanning　the　sinkholes　is　proposed,　containing　different　forms　of　surface　subsidence　and　can　be　applied　to　the　serviceability　limit　state　design　and　the　ultimate　limit　state　design　simultaneously.　The　accuracy　and　rationality　of　the　proposed　method　are　verified　by　comparisons　of　the　current　design　methods　so　as　to　provide　a　reference　for　such　structures.　©　2018,　Editorial　Office　of　Chinese　Journal　of　Geotechnical　Engineering.　All　right　reserved.
