    Abstract
  • Shear strength of high fill loess is an important parameter to analyze the stability of high fill loess slope. To study the influence of moisture content on the shear strength of high fill loess, the shear strength tests of high fill loess with different moisture content (2%, 4%, 6%, 10%, 12%, 15%, 20%, 25%) were carried out, respectively. The experimental results show that when the moisture content is in the range of 2%～25%, the shear strength of high-filled loess increases first and then decreases with the change of moisture content, and reaches the peak when the moisture content is 15%; with the increase of moisture content, the internal friction angle and cohesion of the high-filled loess firstly increase and then decrease, and the moisture content has a great effect on the cohesion; the slope of shear displacement and shear stress curve increases gradually, when moisture content is 12% and 15%, and the relationship between shear displacement and shear stress is basically linear. The experimental results have certain reference value for the stability evaluation of high fill loess slope.
