| Summary: | In order to quickly assess the stability of slopes from the perspective of slope size, this study first conducts Morgenstern-Price method to analyze the influence of slope size parameters on slope stability and scale of the sliding body. Secondly, introduces the slope shape influence factor δ, to quantify the extent of the impact of slope size on slope stability, and finds that the extent of this impact depends solely on the combination coefficient H* (equivalent height). Thirdly, this study analyzes the variation patterns of the slope shape influence factor by considering the effects of groundwater and seismic loads. Finally, by combining charts of the slope shape influence factor with charts of the factor of safety under standard slope conditions (slope height H = 25 m, slope angle β = 35°), a method for calculating the slope factor of safety based on slope sizes is proposed, and corresponding software ICSS-Slope was developed. A comparison of the factor of safeties obtained using the method proposed in this study and the Slide through 9 slope models shows that the maximum error among the 9 models is only 2.42 %, validating the reliability of slope stability assessment based on slope size in this study. |
