Since a large amount of silt foundation in the Longxikou Reservoir area cannot be directly used as the bearing layer for embankments,and the disposal of silt will cause adverse environmental effects,this paper carries out experimental research on solidified soil (with or without stone) embankment materials.After a certain amount of cementitious materials and specialized additives are used to solidify the soil (stone),the cemented soil (stone) has certain advantages such as mechanical strength and impermeability and does not collapse after three years of soaking in water,meeting the strength requirements of embankment materials.The construction of cemented soil (stone) embankment on a silt foundation is innovative.The new embankment building materials enable waste utilization of silt.The safety of the consolidated material is higher than that of the granular material of the traditional embankment dam,and it broadens the application range of embankment building materials and has good promotion and application value.
