独塔单索面曲线地铁斜拉桥关键技术研究

摘要

介绍国内第一座独塔单索面曲线地铁斜拉桥——南京地铁2号线跨仙林大道桥,分析其与常规的直线独塔单索面斜拉桥相比所具有的特点和难点.通过对这种斜拉桥设计中的一些关键技术进行阐述和研究,为以后该类桥梁设计提供一定的借鉴作用.%The paper introduces the first single-pylon, singlecable-plane curved cable-stayed subway bridge in China on Nanjing subway Line 2 crossing Xianlin Road of Nanjing city. Key technologies involved in the course of design are studied and described which may be of help to the design of similar bridges.
