摘要
介绍既有桥梁的概况,建立了桥梁计算分析模型。分析结果表明:加宽改造后既有桥梁结构满足现行公路钢筋混凝土规范要求,为加宽改造后桥梁结构的安全提供理论依据。
This paper has introduced the profile of existing bridges and established bridge calculation analysis model. The results showed that after widening modification, the existing bridges can meet requirements for current highway reinforced concrete specifications which provided theoretical foundation for safety of bridge structure after widening modification.
