摘　　要：结合工程实例,介绍了既有线框构桥加宽接长技术在客运专线建设中的应用,从D型梁运输,装卸等方面探讨了D型便梁装卸及横移的技术及施工工艺,对既有线电气化区段D型梁施工具有一定的参考价值。Combining with some engineering examples,the paper introduces the application of the frame-shaped culvert widening and grating technique along the existing line in construction of the passenger special line,and explores the D-shaped beam loading and unloading and the traversing technique and the construction craft from the D-shaped beam transportation and the loading and unloading aspects,so it has certain reference value of the D-shaped beam construction at electrification section of the existing lines.
