摘　　要：为解决钢塔钢箱梁空间自锚悬索桥原施工方案施工周期长、造价高的问题,创新性地提出一种自锚悬索桥塔梁同步施工技术。创新技术改变了原有方案先进行钢箱梁合龙后进行钢塔安装的方案,通过对施工技术进行创新,采用桥塔与梁同步施工的方式,大幅缩短了施工周期,并节约了施工成本,取得了显著的社会效益和经济效益,亦为类似桥梁工程积累了施工经验。In order to solve the problems of long construction period and high cost in the original construction scheme of steel tower steel box girder space self-anchored suspension bridge,a new synchronous construction technology of selfanchored suspension bridge tower girder is put forward innovatively.Innovative technology has changed the original scheme of installing steel tower after closing the steel box girder first.Through innovating construction technology and adopting the method of synchronous construction of bridge tower and beam,construction period has been greatly shortened,construction cost has been saved,remarkable social and economic benefits have been achieved,and construction experience has also been accumulated for similar bridge projects.
