摘　　要：综述国内外关于桩承式加筋(GRPS)路堤设计理论的研究成果,分析了土拱效应理论和拉膜效应理论。指出了目前桩承式加筋路堤设计理论的不足,提出了GRPS路堤中路堤、桩和土工合成材料三部分设计中有待进一步研究的问题。Design theory of geosynthetie reinforced pile-supported （GRPS） embankments at home and abroad is reviewed. The representative soil arching theory and tensioned membrane theory are analyzed in detail. The shortcomings of the current design theory are pointed out. Furthermore, some key problems in the design of embankments, piles and geosyntheties, which need further study, are presented.

关 键 词：桩承式加筋路堤 土拱效应 拉膜效应
