铁路大桥位于曲线上时，桥梁按折线布置，人行道随梁也成折线布置。在朔黄铁路磊北大桥桥面系 施工过程中，将人行道及扶手做成弧形，不但没有影响人行道的使用效果，而且还增加了大桥的美感。

As the railway major bridge was situated on the railway curves，the bridge beams were usually arranged along as a broken line. Therefore，the sidewalk on bridge beams were arranged also as the broken line. During the construction procedure of the bridge floor system of the Leibei major bridge on the Shuo-Huang Railway， the sidewalk and handrail were constructed according to the arc style， which not only had no influence on the utilization effect of sidewalks，but also increased the aesthetic perception of the major bridge.
