In Instability and Failure of Steep Slope Embankment Test and Numerical Simulation Analysis of MeiHe Expressway in Guangdong Province

Abstract:

In Guangdong MeiHe highway K28 + 360 ~ + 360 section of the steep slope embankment as the research object, by adopting the combination of measurement and numerical analysis methods, analyze the failure process and mode of steep slope embankment. Based on the analyses, The following conclusions were obtained: the sliding surface of fill embankments on slope foundations of K28+360~+860 section was the original surface of the slope. Constructions of the highway would block the groundwater discharge and reduce the strength of the original surface of the slope, which would cause the slide of the fill embankments on slope foundations.
