摘要
桩承式加筋路堤由于其经济性和有效性在道路工程中得到了广泛的应用,近年来许多研究人员对其进行了大量的研究。本文从桩承式加筋路堤的工程应用出发,分析了土拱效应理论和拉膜效应理论,并详细论述了桩承式加筋路堤在试验研究和数值模拟研究方面的进展。基于桩承式加筋路堤的研究现状,提出了有待进一步研究的问题。
Geosynthetic-reinforced pile-supported embankments have been widely used in road engineering due to their economy and effectiveness.Lots of researches have been conducted in recent years.This paper begins with the engineering application of geosynthetic-reinforced pile-supported embankments.It then focuses on load transfer mechanisms,including soil arching effect and tensioned membrane effect.The research progresses of geosyntheticreinforced pile-supported embankments in experimental research and numerical simulations are discussed in detail.Based on the current research status,some problems which need further study are put forward.
