| 摘 要： | 通过分析桥涵台背回填处沉陷及跳车的原因,台背回填应作为单项进行设计,要合理有效地确定桥涵台背回填处刚柔过渡段,并选择易于压实且具有相当刚度的回填材料,同时要加强现场施工管理,只有这样,才能彻底消除或减少桥涵台背回填处的沉陷及跳车问题.

| Abstract: | By analyzing the cause of sinking in the place of bridge culvert deck backfill and bumping, backfill should be designed as independent item and the rigid-flexible transition in the
bridge culvert deck backfill should be ensured reasonably and availably. It also should choose backfill material which can be pressed easily and has a certain rigidity, meanwhile, improve the construction management.If do this, the problem will be solved successfully. |
