摘　　要：分析道路路基沉降、桥头跳车的原因及其对道路和行车的影响,论述软土地区道路病害发生的原因,提出EPS填筑路基可以从根本上解决桥路的差异沉降与路堤的残余沉降,达到防止桥头跳车以及台后填土与地基位移对桥台的侧向作用之目的。EPS填筑路堤可极大减小对地基的压力,其沉降、变位皆小,稳定性好,具有良好的推广价值和运用前景。In order to solve the problem of residual settlement at the road embankment and the jump of bridge, the method of light-soil is presented. The research results show that this application practice is very successful and satisfactory. The pressure on ground can be greatly reduced and the settlement and displacement of the EPS embankment are small. So the EPS embankment is worth applying and spreading.
