以某主跨156 m 的5跨连续双塔双索面自锚式预应力混凝土悬索桥为背景，根据该类桥型的建造特点，讨论了加劲梁、猫道、成桥主缆线形、空缆线形、吊索张拉、索鞍顶推等的控制及分析方法。应用数值分析方法提出了单元选取、边界条件设置、荷载选取、工况模拟的方法。运用上述方法完成了依托桥梁的过程控制，取得了最终成桥主缆高程偏差仅为3．9 cm ，吊索索力相对误差小于4％，主塔偏位最大偏差仅为2．1 cm 和主梁高程误差仅为6．6 cm 的良好控制效果。研究结果表明：所提出的分析方法考虑问题全面，具有较好的控制效果。

Aimed at the problems of analysis for concrete self-anchored suspension bridge ,a main span 156 m five-span prestressed concrete double tower and double cable plane self-anchored suspension bridge was taken as the example bridge .According to the bridge construction process , control and analysis methods were discussed , such as stiffening beam , catwalk , main cable shape ,unloaded cable shape ,suspender tensioning ,saddle pre-offset ,etc .Using the numerical analysis method ,the unit selection ,boundary conditions setting ,load selection and condition simulation were proposed . Process control of the bridge was completed applying the above methods and good control effect was got ,such as final cable elevation deviation was 3 .9 cm , relative error of suspender cable force was less than 4% ,main tower deviation was 2 .1 cm and main girder elevation error was 6 .6 cm . The study results show that the proposed analysis method takes into account the problems comprehensively ,has good control effect .
