Abstract：The paper researched the effect of EN-1 solidifying agent content,curing age,compactness and water content on loess strength and seepage properties by compaction,shear strength and permeability tests.The result indicated that EN-1 solidifying agent can remarkably increase the dry density,shear strength and impermeability;improve the loess mechanical properties.Along with the increase of solidifying agent content,curing age and compactness,the cohesion and internal friction angle increases and the permeability decreases.Along with the increase of the water content,the cohesion and internal friction angle decreases.The paper suggested that the suitable mixing amount of EN-1 soil stabilizer is about 0.01%,the curing age is at least 7 d and the compactness is controlled above 0.95,the water content of solidified soil should under the optimum moisture content a little.
