摘　　要：结合梁济运河大桥工程实例,应用灰色理论建立预测模型,预测各梁段浇筑前后的沉降变形,为施工控制提供参考,使桥梁结构线型符合设计的理想形状。通过与实测沉降变形相比,证明了此模型在桥梁施工控制中具有重要的作用。Combined with practical work of Liangji canal bridge, the predicting model is established by applying the grey system theory ,which provide references for construction control and make the structural line of bridge matching the designed line by predicting the settlement of casting stage. Contrasting with the actual settlement, It is certificated that this model has positive function for construction control of bridge.
