先张法预应力空心板在桥梁施工中得到了广泛的应用,但在实际施工中经常会出现反拱度超过设计要求的现象。针对先张法预应力空心板反拱度产生的成因,文章对先张法预应力空心板反拱度进行计算,分析了引起反拱度偏差的各种原因,提出了施工时为避免反拱度过大应该注意的事项,为先张法空心板反拱度的施工控制提供了参考。
Pretensioned prestressed hollow slab in the bridge construction has been widely used, but in the actual construction of the reverse arching often exceed the design requirements of the phenomenon. In allusion to the causation of the anti-camber of prestressed hollow slab, the paper analyzes the camber of pre-stressed prestressed hollow slab, analyzes various causes of reverse camber deviation, Excessive should pay attention to the matter, for the first Zhang Zhang hollow arch reverse construction control provides a reference.
