摘　　要：对比某斜交混凝土自锚式悬索桥平面模型与空间梁格模型,认为其在施工阶段受力特点与正交桥基本一致,可采用平面模型进行施工阶段的控制计算。通过施工控制前的参数修正及缆索张拉控制,辅以频率法测试吊杆频率等方法,进行了施工控制,取得了较高的施工精度,满足设计成桥要求。In this paper, plane model and crossbeam model of an oblique concrete self-anchored suspension bridge are built to study the stress characteristics and control method in constructing phase. The results show that the characteristics of oblique bridge are similar with the normal bridge. The construction accuracy is weIl controlled and can meet the design requirements based on parameters modification, cable tension control and frequency test of suspension rod during construction process.
