The soil structure changing with the alternate dry-wet affects the strength and permeability of loess.Through the indoor triaxial compression and penetration test[1],the influence of alternate dry-wet on the strength and permeability of loess was shown as follows: with the increase of dry-wet cycles,the strength,cohesion and internal friction angle of remolded loess all decreased.The reduction was the greatest at one cycle;the lower the initial water content was,the more the alternate dry-wet affected the strength;the soil structure was re-balanced,and the strength was stabilized,after a certain number of cycles of dry-wet;and the permeability coefficient increased significantly with the addition of dry-wet cycles.
