粗粒土高填方斜坡路堤变形规律及影响因素分析

Analysis on deformation rule and influence factors of coarse grained soil high fill slope embankment

针对山区高速公路中粗粒土高填方斜坡路堤变形规律复杂、影响因素多的问题,采用可反映粗粒土应变软化与剪胀特性的Naylor的K-G模型进行数值分析,研究了粗粒土高填斜坡路堤变形特征及其影响因素,为今后山区高路堤的设计、施工提供了参考依据。

According to the problems of complex deformation rule and many influence factors of coarse grained soil high fill slope embankment in mountain highway, this paper made numerical analysis used K-G model of Naylor could reflect coarse grained soil strain softening and dilatancy properties, researched the change characteristics and influence factors of coarse grained soil high fill slope embankment, provided references for future design, construction of high embankment in mountainous area.
