预应力混凝土连续箱梁裂缝分析与防治

Crack Analysis and Prevention of Prestressed Concrete Continuous Box Girder

桥梁的建设在现代交通行业中占据了重要的地位,随着交通运输量的逐渐增大,桥梁建设的规模也逐渐加大。桥梁结构形式多种多样,其中,预应力混凝土连续箱梁就是其中典型的一种类型,桥梁建设数量和规模的增大,在一定程度上促进了其施工工艺和技术的成熟和发展,但尽管如此,由于设计施工及后期一些不可抗力的原因,桥梁出现裂缝的情况十分常见。论文针对预应力混凝土连续箱梁的裂缝进行分析,并据此提出一些防治措施,为桥梁的建设和日常防护提供一定的借鉴。

Bridge construction occupies an important position in modern transportation industry.With the gradual increase of traffic volume,the scale of bridge construction is also gradually increasing.There are many kinds of bridge structures,among which the prestressed concrete continuous box girder is one of the typical types.The increase of bridge construction quantity and scale promotes the maturity and development of its construction technology and technology to a certain extent.However,due to the design and construction and some force majeure reasons in the later stage,the bridge cracks are very common.This paper analyzes the cracks of prestressed concrete continuous box girder,and puts forward some prevention measures,which can provide reference for the construction and daily protection of bridges.
