摘　　要：装配式简支梁桥结构分析验算包括截面特性计算、荷载横向分布影响线计算、纵向内力影响线计算、加载、内力计算、结构验算等主要过程。将各计算过程编制成具有相应功能的电算模块,再将各功能模块组装成综合程序,读取用户界面输入的桥梁设计基本参数,自动完成简支梁桥结构计算分析全部内容,并形成固定格式的计算书。结合实例,介绍了装配式预应力简支梁桥电算程序的开发过程。The check calculation on the main procedures of structural analysis of fabricated simply supported girder bridge is made, including calculation of cross - section characteristic, calculation of lateral distribution influence line of load, calculation of influence line of longitudinal internal force, load, internal force calculation, structural check calculation and so on. The calculation processes are made into computer calculation modules with the corresponding function, and then the function modules are assembled into synthesis programs, so as to read the basic parameters of bridge design input by the user interface, automatically finish the entire content of calculation analysis of simply supported girder bridge, and form the calculation sheet with fixed format. In combination with the examples, the development process of computer calculation program of fabricated prestressed simply supported girder bridge is introduced.
