摘　　要：桥梁工程建设规模逐渐扩大,在我国交通运输中发挥了基础性的作用。由于设计与施工方面还存在着一定的弊端与不足,导致桥梁出现病害问题逐渐严重,制约着桥梁在交通运输中作用的发挥,甚至威胁到人们的生命财产安全。由于预应力简支梁在新建桥梁中占据了很大的比例,因此,其病害防治工程愈发凸显重要。对预应力简支梁病害进行了分析、分类,并提出相应的防治措施,作为今后预应力简支梁施工、维护的基本依据。The scale of bridge construction has gradually expanded, which has played a fundamental role in China's transportation. Because there are some disadvantages and deficiencies in the design and construction, the problem of bridge disease has gradually become serious, which restricts the role of bridge in transportation, and even threatens people's life and property safety. Prestressed simply supported beams occupy a large proportion of new bridges. Therefore, their disease control project becomes more and more important. Prestressed simply supported beam diseases are analyzed and classified, and corresponding control measures are put forward as a foundamental basis for the construction and maintenance of prestressed simply suppored beam in the future.
