摘　　要：探讨了运用灰色理论进行大跨度连续刚构桥施工过程控制,通过建立灰色理论计算模型GM(1,1),结合泾河特大桥施工控制进行实践,现场监测该桥施工过程中内力和变形的走势,并将测得结果与计算各梁段的施工预拱度进行对比分析,最终确保成桥成后结构的线形与应力在设计规定的误差范围之内,验证了灰色理论体系在大跨度连续刚构桥施工控制中是可行的。Discussed the grey system theory that is applied in the construction control of the large span continuous rigid frame bridge,taking the construction process control of Jinghe River Bridge as the studying object,establishing grey model GM（ 1,1）,monitoring of the bridge during construction about the trend of internal force and deformation,carrying on comparison analysising between the construction pre measured results and the calculation of beam camber to ensure that the bridge after the structure of linear and stress within the error range of design rules,and confirmed that the grey theory system is feasible in the construction control of the large span continuous rigid frame bridge.
