摘要
结合豫西山区公路黄土边坡,采用非饱和土分析方法,以室内试验获得的黄土物理力学性质指标及土水特征曲线为输入参数,利用数值方法研究了坡度、坡高、气候参数等因素对非饱和黄土边坡湿度场分布和孔压场分布的影响规律,分析了各工况对公路非饱和边坡稳定性的影响,为黄土地区类似工程的边坡治理和安全防护提供参考。
This paper presents evaluation of the slope stability in loess soils in a mountain highway project in west Henan Province by using unsaturated soil mechanics theory. Based on the laboratory tested mechanical and physical properties of loess soils and tested soil-water characteristics curve, potential affecting factors for the loess slope stability, such as, ratio of slope, height of slope and climate, are numerically investigated for the effect of moisture content and pore pressure fields. The loess slope stability analysis results under various working conditions are also provided.
