Abstract：Stabilized soil has goodcompresive，frostresistant，water-resistant，anddrywetcycleresistance properties，and is widelyused intheconstructionof infrastructuresuchaswaterconservancy，transportation，andports.Toimproveits compressive performance，commonsandysoil，loess，andclayin Hebei Province were selected asresearch objects.Through diferent mixratios ofcompresiveperformance tests，theefects ofcement，naphthalene sulfonic acid formaldehydecondensate， anhydroussodium sulfate，silica，flyash，andsodiumchlorideonthecompresivestrength of the materialswereanalyzed. Furthermore，afunctionalrelationshipbetweenthecompresivestrengthofmodifiedfluidizedbedsolidifiedloessandthe compositionratiowas established.Research hasshown that theadditionof naphthalene sulfonicacid formaldehydecondensate andanhydrous sodium sulfatecanimprove thecompressive strengthofcuredpowders；Whenincreasing thedosageofly ashand silica，thecompresive strengthof thesolidified powderfirst increasesandthenremainsunchanged，while increasingthedosage of sodiumchloridecanleadtoanincreaseandthenadecreaseinthecompressivestrengthof thesolidified powder.Theresearch results can provide reference for the application of solidified soil.
