摘要
研究目的:解决小半径曲线地段桥上无缝线路设计的难题。研究结论:小半径曲线地段桥上无缝线路设计应重点从提高线路横向阻力、降低桥上无缝线路钢轨附加力、适当提高设计锁定轨温等几方面考虑。
Research purposes: To solve the problems on designing continuous welded rail on bridge in the small radius curve section.
Research conclusions:When designing continuous welded rail on bridge in the small radius curve section, these factors should be especially considered : increasing lateral ballast resistance, reducing additional forces of the continuous welded rail on bridge, and properly increasing the design stress - free temperature of rail.
