不等线间距铁路桥梁曲线布置新方法

结合工程实际,详细介绍了不等线间距铁路桥梁曲线布置新方法——即把内外两条曲线当作两条单线,分别进行曲线布置,在交点距满足其最小梁缝要求的条件下,再通过两线桥墩台处交点横向连线和拨角来确定两线的相对位置,指出该方法适用范围广、灵活、简捷、方便,具有实用价值。

On new methods for bridge curve layout at different line distance railways

Combining with the engineering fact,the paper mainly introduces the new method to layout the bridge curve along the different line distance,that is,to allocate the curve by treating the two lines inside and outside as the two single lines,and indicates the relative location of the two lines can be identified by the horizontal line and the pulling angle of the bridge pier,and points out the method is flexible,easy to be used,and can be further extended with practical value.
