| 摘 要： | 本文根据大跨径、大制作段及后加临时支撑的钢-混凝土组合梁的设计计算,结合工程实际对钢-混凝土组合梁桥的各个施工阶段的内力、各控制点位移,临时支撑及永久支撑的反力变化效应进行了分析.而文中工程根据分析成果及实测变形监控数据,通过双控原则采取措施调整后,使这种简支钢-混凝土组合梁顺利建成,完全达到了设计的预期要求并为类似工程获取了经验.

| Abstract: | A long span. large fabricated section and with temporary support of steel-concrete composite beam's design calculation, integrated with engineering practice of steel-concrete composite beam bridge's each constructional phases, the internal force, deformation of control point,temporary support and permanent support reaction's variation effect are analysed in the paper. Based upon result of analysis and deformation monitoring data through double control principle after regulation, this simply supported steelconcrete composite beam is successivelly operated and meets the design expected demands and gets experience. |
