Abstract
In this paper, the shear strength experiment of unsaturated coal-bearing soil under dry-wet circulation was carried out on the conventional direct shear apparatus, the relationship between shear strength and its index parameters and water content of unsaturated coal-bearing soil was obtained. The tests show that the total stress shear strength of unsaturated coal-bearing soil was obviously affected by moisture content, and the shear strength decreases with the raise of moisture content, and the total cohesion and total internal friction angle of unsaturated coal-bearing soil are greatly affected by moisture content, which decreases with the raise of water content.
