摘要
以甘肃省内武罐高速公路北段沿线周边1 km区域为研究对象,利用有限元数值模拟软件,通过定量分析,研究了不同地震概率水准下,边坡坡度变化对边坡稳定性的影响关系。分析结果预测了在不同的地震概率水准下,区域内边坡稳定性分布情况,为公路沿线灾害治理及灾害快速评估、确保公路的安全性提供重要的参考依据。
Taking one kilometer area along Wuguan highway around in Gansu province as the research object,through the finite element numerical simulation software and the quantitative analysis,It could research at the different seismic probabilities level slope change on the influence of the slope stability.The calculation results predicted different seismic probability level within the area of slope stability distribution,which rapidly made the assessment of disaster management and disasters along the roads,as well as ensured the safety of highway to provide important reference.
