浅谈钢纤维混凝土在桥面补强中应用

Comment on the application of SFC in strengthening the bridge deck

从施工实践出发,简要介绍了钢纤维混凝土这种新型高强度复合材料在桥面补强中的应用,从而有效解决了因桥面预制空心板梁顶板厚度不足而造成的不利影响。实践证明,采用该种材料补强,不但减小了经济损失,而且很好地保证了桥面的使用要求及寿命。

Based on the construction practice, the article takes a brief introduction of the application of SFRC, a new kind of composite material with double-strength in strengthening the bridge deck and being rid of the disadvantageous effects caused by the lack of the thickness of the beam panel of the precuts hollow slab. It proves that strengthening with this kind of material not only reduces the economic loss but also guarantees the normal usage of the bridge deck.
