双幅联体塔斜拉桥景观设计研究

研究目的：天津南仓立交桥主桥为双幅桥面、四索面独塔斜拉桥,结构形式新颖独特。根据其特点,设计出结构合理、景观效果突出的桥梁结构造型。研究方法：结合桥塔、主梁、斜拉索及桥梁色彩等各部分,采用结构与艺术相结合的研究方法。研究结果：探索出一套针对斜拉桥景观的设计方法,该方法体现结构与景观结合、技术与艺术结合、桥梁与周边环境结合的思想,为同类桥梁的景观设计提供参考。研究结论：在斜拉桥结构造型设计中,桥塔设计是最为关键的。双宝瓶联体桥塔满足双幅桥面使用要求,受力合理、均衡,同时具有良好的桥梁景观效果。此外还应注重主梁、斜拉索以及色彩等方面的设计。

Bridgescape Design Study of Coalescent Towers Cable-stayed Bridge

Research purposes:The Nan-Cang Bridge in Tianjin is a cable-stayed bridge with 2-beams and 4-cable planes.We design the bridge with good structure characteristic and good bridgescape according to its characteristics.Research methods:Combining with the bridge tower,main beam,cabal and bridge color,this paper applies the research method witch integrates structure and art.Research results:The paper explored a set of design experience for bridgescape of cable-stayed bridge,which incorporates structure and bridgescape,technology and art,bridge and entironment.And it provides the references for similar bridgescape design.Research conclusions:In the shape design of cable-stayed bridge,the tower is pivotal.Coalescent towers cable-stayed bridge accord the condition of two-bridge-floors.Its behavior in mechanics is logical and balanced.At the same time,it has good effect of bridgescape.Furthermore,we should pay attention to the design of beam,cable and color,etc.
