浅谈跨径10m中、小桥梁上部构造的选择

对10m跨径桥梁而言,除特殊地形、地质条件外,较为广泛应用的桥梁上部构造是简支空心板或近年来普遍采用的先简支后桥面连续的简支空心板构造;目前,业内对10m跨径桥梁究竟采用钢筋混凝土还是采用预应力混凝土简支空心板上部构造存在异议。通过技术、经济分析以确定何种上部结构形式更为合理。

Simple Talking about Choice of Superstructure of Mid and Minor Bridge with 10m Span

For bridge with 10m span,except for particular topography and geological conditions,the superstructure of bridge widely applies the simply-supported voided slab,and in the recent years generally adopts first the simply-supported then the simply-supported woided slab with a continuous deck.At present,for bridge with 10m span,its superstructure adopts on earth the reinforced concrete or the simply-supported concrete voided slab prestressed,there are still the objections.The paper will determine what kind of superstructure is more rational by way of technical and economical analysis.
