(2) At low moisture content, the internal friction angle decreases with the increase of dry density, and shows fluctuating change with dry density at medium moisture content, and dry density has little effect on the internal friction angle at high moisture content; due to the lubrication effect of water, the internal friction angle shows a decreasing trend with the increase of moisture content.
