Abstract：Thesoftsoiliswidelydistributedinthe mountainous areaofGuizhou province，China，and geologicaldisasters such aslandsldes haveocured.The mixtureofblastfurnaceslagandflyashcaneffctively strengthensoft soil.Basedonthis， solidifiedsoftsoiltestmateralswithdiferentcontentsofblastfumaceslagandflyashwereprepared，andmechanicalpropertis suchasunconfinedcompresivestrength，elasticmodulus，cohesion，internalfrictionangleandwaterstabilityweretested. Theinfluencesofdiffrent blast-fumaceslagandflyashcontentsandratioofblast-furmaceslagandflyashcontentson solidified soft soil wereanalyzed.Theresultsshow that：thecompresivestrength，elastic modulusandcohesionof the solidifiedsoftsoil increasewiththeincreaseofthetotalcontentofflyashandblastfurmaceslag，andtherecommendedtotal content is 18%～24% . When the ratio of fly ash to blast furnace slag is 3：7 ，the compressive strength，elastic modulus and shearstrengthofsoftsoilarethebest.Thewaterstabilityofthesolidifiedsoftsoilincreaseswiththeincreaseof thetotal content，and the recommended total content is 24% . The research results can provide an effective material ratio basis for soft soilfoundationreinforcementandgeologicaldisasterpreventioninGuizhoumountainousarea，andalsoprovideausefuleference for the resource utilization of industrial solid waste in geotechnical engineering.
