In order to study the effects of loess solidified by chemical materials, a series of indoor experiments are conducted to analyze the properties of the raw loess of Taiyuan before and after treated by mixed with varying contents of new polymer-soil stabilizer (SH) and cement. The results of compressive strength, direct shear and permeability tests show that the engineering properties of the loess are improved by SH or cement. The strength and impermeability of solidified loess with chemical solidified materials are better than the raw loess. The properties of strength increased with the content of solidified agent, its density and curing time, but the permeability coefficients decreased. The suitablecontent of mixed SH or cement is about 10%. SH is a new polymer-stabilized agent of water-solubility its less cement dosage, cheap price, high strength, low permeability and no disintegrating effect on loess, SH is SH can be taken into consideration according to practical situation. Because of better than cement, SH can be taken into consideration according to practical situation.
