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。
斜塔無揹索斜拉橋受力特性與常規的直塔斜拉橋有較大的差異，造成瞭其設計以及施工的特殊性。本文以長沙洪山大橋為工程揹景，對無揹索斜拉橋的受力特性、施工以及橋塔的重量分佈和傾角進行瞭探討，為今後同類橋樑的結構設計提供瞭參攷。
사탑무배색사랍교수력특성여상규적직탑사랍교유교대적차이，조성료기설계이급시공적특수성。본문이장사홍산대교위공정배경，대무배색사랍교적수력특성、시공이급교탑적중량분포화경각진행료탐토，위금후동류교량적결구설계제공료삼고。
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.
