Stability Analysis of Loose Accumulation Filling Slope
Based on the field investigation and measured data along an expressway in Sichuan Province,this paper uses Ansys software to establish a numerical model of loose accumulation filling slope along the expressway,and analyzes the factors affecting the stability of loose accumulation such as the height of accumulation filling,the width of top platform and slope.By changing the parameters such as the unilateral height and slope of the filling slope,the safety factor,internal stress and slope toe displacement of the accumulation slope are simulated and analyzed.The results show that the slope grading construction method can effectively improve the stability of the loose accumulation filling slope,and the change of the lower slope parameters plays a decisive role in the stability of the filling slope.
