摘要
 本文以鐵路簡(jiǎn)支梁橋?yàn)槔�，介紹了鐵路簡(jiǎn)支梁橋的主要截面形式，適用范圍，鐵路簡(jiǎn)支梁橋在國(guó)內(nèi)外的發(fā)展現(xiàn)狀，在國(guó)內(nèi)的施工工藝，設(shè)計(jì)計(jì)算方法以及優(yōu)缺點(diǎn)。這里重點(diǎn)介紹了鐵路簡(jiǎn)支梁橋的設(shè)計(jì)計(jì)算方法。
 簡(jiǎn)支梁橋的設(shè)計(jì)計(jì)算方法大致可分為兩個(gè)方面：主梁的設(shè)計(jì)和橋墩的設(shè)計(jì)。主梁的設(shè)計(jì)主要是通過(guò)選定簡(jiǎn)支梁的主梁截面形式，擬定截面尺寸，然后根據(jù)設(shè)計(jì)資料，應(yīng)用《混凝土結(jié)構(gòu)設(shè)計(jì)原理》、《橋梁工程》的相關(guān)知識(shí)及有關(guān)規(guī)范，進(jìn)行荷載組合，計(jì)算主梁內(nèi)力，選擇主筋，并對(duì)鋼筋和混凝土進(jìn)行應(yīng)力驗(yàn)算，然后根據(jù)計(jì)算數(shù)據(jù)選擇腹筋，另外為滿足構(gòu)造要求，還要對(duì)架立鋼筋、分配鋼筋等進(jìn)行選擇，最后對(duì)主梁進(jìn)行裂縫寬度和撓度驗(yàn)算。橋墩的設(shè)計(jì)主要包括荷載計(jì)算，主力和附加力的計(jì)算，墩身、墩底截面的橫向驗(yàn)算及縱向驗(yàn)算，然后對(duì)鋼筋進(jìn)行選擇。最后總結(jié)在設(shè)計(jì)過(guò)程中的心得體會(huì)，提出在設(shè)計(jì)過(guò)程中需要改進(jìn)的地方，并在以后的學(xué)習(xí)過(guò)程中加以改進(jìn)。

Abstract
 In this paper, simply supported railway bridge as an example, the railway bridge beams form the main section, the scope of application, the railway bridge Beam current development at home and abroad, in China's construction technology, design    and calculation methods and the advantages and disadvantages. Here focuses on simple beam bridge rail design method.
 Beam bridge design methods can be broadly divided into two areas: the design of the  main beam and pier design. The design of the main girder is simply supported beam through the selected section forms the main beam to draw cross-section dimensions, and according to design information, application of "concrete structural design," "Bridge," the relevant knowledge and the related codes for load combination, calculate the internal force main beam, select the main reinforcement, and steel and concrete for stress check, and then select the web reinforcement calculations, other construction requirements to meet, but also on the erect steel, reinforcement and distribution of select, the final crack width of the main beam and deflection checking. Pier design include load calculation, the calculation of main and additional force, piers, pier checking the bottom section of the horizontal and vertical checking, and then select bar. At last, in the design process of their feelings and experiences, put forward in the design process needs improvement, and in the future to improve the learning process.
