摘　　要：桥梁支架结构类型丰富多样,合理的支架施工工艺是施工质量和安全的保证,沙河大桥跨规划石桥路(40+56+40)m连续梁支架采用贝雷梁+碗扣式支架形式,支架基础采用桩基础,桩顶设钢筋混凝土联系梁。施工过程中,通过预压手段消除弹性变形及塑性变形,以确保结构的安全。The structure types of the bridge support are rich and varied, and the reasonable support construction technology is the guarantee of construction quality and safety. Shahe Bridge across planning Stonebridge Road（40 ＋ 56 ＋ 40） m continuous beam support is the Bailey beam ＋ bowl buckle scaffold form and the bracket is based on the pile foundation, and the top of the pile is provided with a reinforced concrete connection beam. In the process of construction, the elastic deformation and plastic deformation are eliminated by preloading, so as to ensure the safety of the structure.
