The invention provides a cable-stayed bridge building method, wherein calculation software is used for simulating and reversely deducing deflection angles of cable bent towers and steel beams in all stages in the cable-stayed bridge building process, and when construction is completed, the cable bent towers and the steel beams just return to design requirements. In the process, counterweight operation is not needed, the cost is saved, the operation efficiency is high, and the operation efficiency is improved by about 40% compared with a construction method for building a cable-stayed bridge by using a counterweight. 本发明提供了一种斜拉桥修建方法，利用计算软件模拟倒推出在修建斜拉桥的过程中各个阶段索塔和钢梁的偏斜角度，到施工完成时，索塔和钢梁刚好回归设计要求。该过程中不需要进行配重作业，节约成本，作业效率高，相对使用配重修建斜拉桥的施工方法，作业效率提高40％左右。
