| Abstract: | 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. |
