摘要
凤翔路快速化改造工程02标跨沪宁高速钢桁梁为两跨连续梁,跨径165 m+90 m布置,采用无竖杆的三角桁架。钢桁梁在工厂制造,工地拼装。各构件间连接全部为焊接。主桁平面位于直线上,立面位于缓和曲线-2.5%纵坡上。钢桁梁施工设置98 m导梁,采用拖拉滑移方式跨越沪宁高速。
The steel truss beam bridge spanning Shanghai-Nanjing Expressway in Bid 02 of Fengxiang Road Rapid Reconstruction Project is a two-span continuous beam bridge with the layout of 165 m+90 m span.The triangle truss without vertical bar is used.The steel truss beams are manufactured in factory and assembled on site.The connection between the members is all welded.The plane of the main truss is on a straight line and its fa?ade is on a-2.5%longitudinal slope of easement curve.The 98-m guide beam is set for the construction of steel truss beam,which spans Shanghai-Nanjing Expressway by the dragging and slipping method.
