大跨度预应力混凝土连续刚构桥设计理念研究

Study on the Design Concept of Long-Span Pre-Stressed Concrete Continuous Rigid Frame Bridge

桥梁结构是促进国家经济发展的重要交通设施,其建设步伐也逐年加快。大跨度预应力混凝土连续刚构桥作为一种变形较小、刚度较大、性能好、外观简洁美观的新型桥梁形式,在桥梁工程设计中的应用范围日益扩大。为了提高我国桥梁结构的建设水平,探讨了大跨度预应力混凝土连续刚构桥运营期间存在的问题,研究了大跨度预应力混凝土连续刚构桥的设计方法,并对其设计关键点展开了详细的说明。

Bridge engineering is an important infrastructure to promote economic development,and its construction pace is accelerating day by day.As a new type of bridge structure with small deformation,large stiffness,good performance,strong seismic performance and concise appearance,long-span pre-stressed concrete continuous rigid frame bridge has been widely used in bridge engineering construction.In order to improve the design level of long-span pre-stressed concrete continuous rigid frame bridge,this paper analyzed the problems existing in the operation of long-span pre-stressed concrete continuous rigid frame bridge,discussed the design method of long-span pre-stressed concrete continuous rigid frame bridge,and explained its design points in detail.
