【摘要】 介绍了房山五渡桥多种钢-混凝土结合段设计方案对比,分析各种常规桥梁中使用的钢-混凝土结合段构造优缺点,在其基础上通过优化构造,构思了一种新的钢-混凝土结合段构造,即内法兰预压式钢-混凝土结合段构造,拓宽了钢-混凝土结合段构造处理的新思路,达到了构造合理、安全经济、外形美观、施工方便的目的。更多还原

【Abstract】 This paper introduces the comparison of several design schemes of steel-concrete joint segment for Wudu Bridge,analyzes the advantages and disadvantages of all kinds of steel-concrete joint segment structures used in the conventional bridges. On the basis,a new idea for the steel-concrete joint segment structure is conceived by optimizing the structure,namely‘inside flange preloading type steel-concrete joint segment ’structure, which widens the new thought of steel-concrete joint segment structure treatment,the target is achieved including reasonable structure,safety and saving,beautiful appearance and convenient construction.更多还原
