Abstract 为了在中小跨径桥梁中推广使用钢-混凝土组合结构桥梁,提高桥梁的工业化建造水平和组合梁桥的装配化程度,提出了一种整体预制钢-混凝土组合梁桥结构。结合常用的中小跨径的需求,考虑公路运输条件和吊装能力,构建了整体预制钢-混组合梁结构基本单元,并提出了单元之间的连接方式,进一步形成整体桥梁。计算分析表明:所提出的整体预制钢-混组合梁,在受力性能方面均优于传统分离预制钢-混组合梁,在全寿命周期的经济性能方面优于现有的预制混凝土箱梁、预制混凝土T形梁,在施工性能方面相比于现有的预制混凝土箱梁、预制混凝土T形梁以及分离预制钢-混组合梁会明显提高施工效率、缩短施工工期,而且更容易保证施工质量,为桥梁工程提供了一种结构合理、施工便捷的结构形式。
