高填方顺层陡坡路堤防护支挡设计研究

A dissertation on research on protective supporting and retaining designing of high embankment with steep bedding slope

由于横坡较陡,高填方顺层陡坡路堤常常存在滑塌变形的风险。为设计S304省道K7+500~K7+580左侧高填方顺层陡坡路堤的防护支挡方案,以该段填方路堤的工程地质条件为背景,以剩余下滑力稳定性分析计算为手段进行分析。以剩余下滑力作为比选参数,确定桩板墙作为该段高填方顺层陡坡路堤的防护支挡方案。

Many high embankment with steep bedding slopes take the risk of sliding deformation because of the cross slope is very steep. To design the protective supporting and retaining of the K7 ＋ 500 ~ K7 ＋ 580 high embankment with steep bedding slope in S304 provincial highway , the engineering geology is taken as the background and the residual stability analysis is taken as the basic. The protective supporting and retaining designing of pill walls have been designed based on the different residual force curves.
