东营黄河公路大桥系杆拱桥设计

The tie-bar arch bridge design of Dongying Huanghe River Bridge

概述了东营黄河公路大桥的桥型选用、结构总体布局及结构各阶段的内力分析 ,阐述选用外部静定的自锚式系杆拱结构以适应在新近沉积的软弱性土层上建桥的优越性和结构总体布局的有效性、合理性。通过对结构各阶段内力计算的详细介绍 ,论述了转体法施工及钢管混凝土等新技术、新材料运用于拱桥修建技术的安全。

In the paper the selection of bridge type, overall structural layout and internal force analysis of structure are summarized. The superiority and the validity and the rationality of overall layout of choosing external static self anchored tie bar arch bridge to adapt the soft soil layer. Through the detail introduce of internal force analysis of several structure stages the advanced design thought of adopting the rotating method construction, concrete filled steel tube and other new technologies and new materials to construct arch bridges are discussed.
