Abstract: The artificial water-repellent soils were prepared with octadecylamine. Then the shear strength tests were carried out under the different conditions, including the solute composition, solution concentration and immersion time, and the corresponding change laws of shear strength were obtained. The results show that the shear strength of samples are improved with the increase of the concentration of oxalic acid, sodium bicarbonate and copper sulfate solution; and reduced with the increase of the concentration of AEO-9 and sodium bicarbonate solution. While, the concentration of 6501 (coconutt diethanolamide) and water-soluble azone have little effect on the shear strength of samples. In general, the influencing degree of solution concentration on shear strength of samples are shown from high to low as follows: copper sulfate, oxalic acid, water-soluble azone, AEO-9, 6501 and sodium bicarbonate. Besides, the effects of organic solution on the shear strength of water-repellent soils are greater than that of inorganic solution, and the shear strength become stable as time goes on.
