以重庆轨道交通3号线二期工程区间高架桥为背景，从景观效果、节约投资、方便施工等多个方面对标准桥墩结构型式进行对比分析；针对梁跨较小的情况，提出跨越道路交叉口的优化结构方案，研究提出了中央分隔带内桥墩和道路交叉口独立桥墩的防撞措施设计。结果表明，与双薄壁墩相比，矩形墩具有结构受力合理、景观效果好、施工方便、节省投资等优点，适用于城市轨道交通高架桥。
以重慶軌道交通3號線二期工程區間高架橋為揹景，從景觀效果、節約投資、方便施工等多箇方麵對標準橋墩結構型式進行對比分析；針對樑跨較小的情況，提齣跨越道路交扠口的優化結構方案，研究提齣瞭中央分隔帶內橋墩和道路交扠口獨立橋墩的防撞措施設計。結果錶明，與雙薄壁墩相比，矩形墩具有結構受力閤理、景觀效果好、施工方便、節省投資等優點，適用于城市軌道交通高架橋。

Taking section viaduct of Phase II on Chongqing line 3 as an example, the paper makes comparison and analysis on a standard pier structure type from many aspects including landscape effect, saving investment, and accessible construction. For short span beam, scheme of optimized structure to across road intersection is proposed. The study presents the anti-crash measure design for the piers in central median and independent pier at road intersections. The results show that pier of rectangular structure has reasonable force, better landscape effect, convenient construction, saving investment, etc. when compared with the double-thin wall pier, and they are applicable to rail transit viaduct.
