摘要
本设计采用预应力混凝土连续梁体系,跨径布置为3×40 m,主梁为T梁.跨中梁高为2.0 m.桥墩为C25钢筋混凝土双柱式圆形墩,基础为C25钢筋混凝土钻孔灌注桩基础.该文主要阐述了该桥的设计和计算过程.首先进行桥型方案比选,对主桥进行总体结构设计,然后对上部结构进行内力、配筋计算,再进行强度、应力及变形验算,最后进行下部结构验算.
The bridge belongs to the prestressed concrete structure which is a continuous beam system. The span arrangement is 3 × 40 m. The supemtructure is girder. The height of the girder on the support is 2.6m, The abutment is double column - like pier of C25 reinforced concrete. And the foundation is the cast - in - place pile. This essay focuses on the design and calculation process of the bridge. Fimtly, a best scheme was compared and chosen from several bridge types; and an overall structure design of the main span was made. Secondly the internal force and reinforcing bar on the supemtructure was calculated. Thirdly, the intensity, stress and deflection was checked. Finally the substructure was examined.
