摘　　要：反压护道是软基上道路施工路堤防护的一种常见措施,本文首先简述了反压护道的原理,采用拉格朗日快速分析法(FLAC)对广州番禺某道路反压护道措施的高宽度设计进行了数值模拟,着重探讨了路堤稳定性随反压护道高度、宽度及两者比率的变化规律,得到了一些有益的结论,对道路施工反压护道的优化设计提供了有价值的参考。Back berm is a common method for embankment protection on the soft soil foundation.First,the principle of back berm is briefly introduced in this paper.Fast Lagrangian Analysis Method(FLAC) is carried out to simulate numerically the height width design of back berm for a road constructed in Panyu District,Guangzhou City.The variation law of embankment stability with different back berm height,width and ratio between height and width is mainly discussed.Some useful conclusions are obtained to provide valuable reference for optimal design of road construction back berm.
