夜郎湖特大桥方案设计

Scheme Design of Bridge Lake Yelang

结合工程实例,考虑桥梁结构适用、经济、安全、美观、环保等要求,对夜郎湖特大桥采用钢筋混凝土箱形拱桥、预应力混凝土连续刚构桥、钢管混凝土拱桥等桥型方案进行分析比选,得出钢筋混凝土箱形拱桥为最优方案。

With engineering examples, considering suitability, economy, security, artistry, environ mental protection of bridge structure and so on, this paper carries on the analysis to select schemes of the reinforced concrete box arch bridge, the prestressed concrete continual rigid frame bridge and the concrete-filled steel tubular arch bridge to Bridge Lake Yelang and draws a conclusion for the best scheme of the reinforced concrete box arch bridge, with the guidance of the project.
