Study on Failure Mechanism and Stability of Loess Slope in Huangshui River Basin

Abstract:

This paper shows the result of the research on the stability of loess high slopes with 30m and 80m in Huangshui River basin. The investigations carried out the numerical simulations of the slope stability based on the drilling and sequence sampling test in a typical loess stratum of the survey region. The result shows that the mechanisms of fracture related to the gradients of slopes are different and the limit equilibrium angles of slopes are 60° and 37° respectively.
