Abstract On the certain condition of soil and certain amount of soil stabilizer dosage,density and water content are the key factors to effect on the unconfined compression strength of the catchments area with soil stabilizer.The rule of solidified soil intensity influenced by density and water content is studied.The results indicated that the density influenced the strength more than water content.Along with the increase of the density,the unconfined compression strength increases straightly.Under the same density,the strength was the greatest if the water ratio lies in the field from 75% to 85% of the optimum water content.If the water content wasn't in the scope,the unconfined compression strength of solidified soil descended straightly.This test shows that solidified soil should be compacted as much as possible and the compactness should be above 0.94 in the catchments area construction.The water content should be from 80% to 90% of optimum moisture content.
