铁路道口安全与框构桥设计软件实现

铁路平交道口是铁路运输中常发生列车和汽车事故的地方 ,在列车经过平交道口时 ,汽车和行人等都必须停在道口两侧 ,严重地影响了交通安全 ,甚至有火车与熄灭在道口的汽车相撞 ,造成火车脱轨的重大事故。因此 ,平交道口改为立体交叉已势在必行。笔者提出了将平交道口改建为框构桥的设计方法 ,并用面向对象的程序设计方法实现了框构桥的自动设计、分析、计算及绘图等过程 ,将极大提高框构桥设计的工作效率 ,加快平改立的速度 ,尽快消除安全隐患

Safety of Railway Crossing and Software Realization in the Design of Frame Bridge

Railway grade crossing is the place where most traffic accident between train and car happened. When the train is passing the crossing, cars and pedestrians must wait at two sides causing traffic jam and seriously affecting traffic safety. Therefore to rebuild grade crossing into grade separated interchange is imperative. The authors present a design method of rebuilding the railway grade crossing to frame bridge, and then realizing the whole process of automatic design, analysis, computation and draft output using the object oriented program design method for the frame bridge. This will improve the efficiency of frame bridge design, expedite the speed of rebuilding railway grade crossing into grade separation interchange, and eliminating the hidden danger as soon as possible.
