横系梁的设置对加强桥梁的整体受力很有好处,横系梁的合理数量和合理位置就显得尤为重要。基于三维实体模型从应力水平和结构位移两个方面对无桥台斜腿刚架桥横系梁的设置进行了分析,研究结果表明:主孔和副孔跨中横系梁、主梁梁端横系梁、斜腿与主梁相交处横系梁必须设置,且横系梁的数量并非越多越好。 The setting of transverse beam is very good for strengthening the whole force of the bridge, and the reasonable number and reasonable position of horizontal beam are very important. Based on the three-dimensional solid model, the arrangement of transverse girder of bridge without bridge abutment and inclined leg rigid frame bridge is analyzed from two aspects of stress level and structural displacement. The results show that: Cross-beam, oblique leg and the main beam intersection of the horizontal beam must be set, and the number of horizontal beam is not the better.
