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的目的。
In this article, authors analyze reasons of sedimentation of road foundation and car-jumping at end of bridge and their influence on road and driving, discuss reasons of road flaws in soft soil areas, provide that EPS reclaiming road foundation can solve the problem of sedimentation difference of road and bridge, and the problem of residual sedimentation of road bank and can prevent car-jumping at end of bridge and lateral action of displacement of post-backfill and foundation on piers. EPS reclaiming road bank can effectively decrease pressure on foundation, its displacement and deformation are very small, and it has good stability and application prospects.
