摘　　要：斜塔无背索斜拉桥受力特性与常规的直塔斜拉桥有较大的差异，造成了其设计以及施工的特殊性。本文以长沙洪山大桥为工程背景，对无背索斜拉桥的受力特性、施工以及桥塔的重量分布和倾角进行了探讨，为今后同类桥梁的结构设计提供了参考。The characteristics of inclined pylon cable-stayed bridge without back stay is different from straight tower cable-stayed bridge, lead to the particularity of its design and construction. Taking Changsha Hongshan bridge engineering as the example, and discusses the stress characteristics, co-nstruction of cable-stayed bridge without back stay and weight distribution and dip angle of bridge tower, so as to provide certain reference for the similar bridges structural design.
