摘  要
 梁式橋是我國一種非常普遍的橋型，它的適用范圍較為廣泛。簡支梁橋在小跨徑的梁橋中使用十線路為平坡、直線。采用雙片肋式T形截面，道碴橋面，設雙側帶欄桿的人行道，橋下凈空5m，本橋設計采用多跨簡支梁橋方案，計算跨度采用16m。本橋所承受的荷載分恒載和活載兩種。本設計重點研究的問題是內力計算和配筋計算。通過分廣泛，施工方便，技術成熟。
 本橋為單線鐵路橋，位于城市的郊區，橋上設計進一步鞏固鋼筋混凝土基本原理的主要理論知識，掌握橋梁的設計原理和各種體系橋梁的受力特點，同時重點掌握結構計算基本理論。

Abstract
 Beam Bridge is a very popular Chinese bridge, its broader scope. Simple beam bridge in a small span of the bridge using 10 lines for the flat slope, straight line. Double T-shaped fin, ballast deck, located both sides with railings on the sidewalk, bridge clearance 5m, the bridge design uses a multi-span simply supported bridge with calculated span by 16m. Loads of the bridge divided by the dead load and live load of two. The design focuses on the problem is internal force calculations and Reinforcement. Through the sub-extensive, convenient construction, maturity of the technology.
 The bridge is single-track railway bridge, located on the outskirts of the city, the bridge design to further strengthen the basic principles of reinforced concrete the main theoretical knowledge, master bridge design principles and various mechanical characteristics of the bridge system, with emphasis to grasp the basic theory of structure calculation.
