在科技和经济的支持下,桥梁的结构形式也越来越多,其中预制小箱梁在桥梁设计中得到广泛的应用。但是由于受到各方面的限制以及各种原因的影响,我国桥梁设计中的小箱梁结构中还存在着诸多问题,尤其以裂缝为主。文章主要探究了预制小箱梁中常见的几种裂缝的类型,并对出现裂缝的原因进行了分析,总结探究防治裂缝的措施和手段。

With the support of science and technology and ec-onomy, the bridge structure form is also more and more, in wh-ich the precast smal box girder is widely used in bridge design. But due to various constraints and reasons, there are many pro-blems in smal box girder structure design of bridges in our co-untry, especial y in the fractures. This article mainly discusses several types of common concrete cracks in precast smal box girder, and analyzes the causes of cracks, summarizes the me-asures and means of crack prevention.
