摘要
沪苏湖高速铁路作为长三角核心区一条重要的铁路运输通道,在苏州吴江区连续小角度跨越申嘉湖油气管线、常台高速、乍嘉苏航道。为取得合理的桥式方案,针对(92+168+142+82)m刚构连续梁桥,(40+168+40)m系杆拱连续梁桥,(35+168+136+35)m混凝土独塔部分斜拉桥3个桥式方案进行对比分析。经过对比可知:(35+168+136+35)m混凝土独塔部分斜拉桥具有新颖美观、经济合理,施工便捷,养护工作量小等优点,是本桥的最佳方案。
As an important railway transportation channel in the core area of the Yangtze River Delta,the Shanghai-Suzhou-Huzhou High-speed Railway crosses the Shenjiahu Oil and Gas Pipeline,Changzhou-Taizhou Expressway,and Zhapu-Jiaxing-Suzhou Channel in a small angle in Wujiang District of Suzhou City.In order to obtain a reasonable bridge scheme,the three bridge schemes of(92+168+142+82)m continuous rigid frame bridge,(40+168+40)m tied arch continuous beam bridge and(35+168+136+35)m concrete single tower partial cable-stayed bridge are compared and analyzed.The results show that(35+168+136+35)m concrete single tower partial cable-stayed bridge is the best solution for the bridge.It is fashionable and attractive,economic and rational,and convenient for construction with less maintenance.
