某公路边坡稳定性分析及治理

Analysis and Control of Slope Stability of a Highway

在山区公路的修建过程中,往往会形成各种边坡。山区公路边坡由于地质构造、水文气象等情况比较复杂,导致这些区域容易出现滑坡等灾害。针对云南某在建公路工程形成的边坡,对其进行工程地质调查与勘测,查明了边坡区域的物质结构、地形地貌、人类工程活动、水文环境勘测等数据,从理论上分析了公路边坡的稳定性,利用不平衡推力法定量地计算了在天然、暴雨、地震状态三种工况的稳定性,得出边坡处于不稳定状态的结论。为了保证拟建公路正常运行,防止坡体滑移,结合现状对该边坡不稳定区域提出防治措施,为以后山区公路边坡的治理提供参考方案。

In the construction process of mountain roads,various slopes are often formed.Because of the complex geological structure,hydrometeorology and so on,the mountain highway slope is prone to landslide and other disasters.In view of the slope formed by a highway project under construction in Yunnan,the engineering geological survey and survey are carried out,and the data of material structure,topography and geomorphology,human engineering activities and hydrological environment survey in the slope area are found out.The stability of the slope is analyzed theoretically.In order to ensure the normal operation of the proposed highway and prevent the slope body from slipping,combined with the present situation,the prevention and control measures are put forward for the unstable area of the slope,which provides a reference scheme for the treatment of the mountain highway slope in the future.
