马鞍山长江公路大桥采用了国内外少见的多塔悬索桥方案,为国内首次提出此种桥型方案,其跨度目前与泰州长江公路大桥并列位居世界同类型桥梁第一。经近5年的资料收集与前期研究,大桥方案最终得以顺利实施。本文介绍马鞍山大桥的前期桥型方案选择原则和设计方案的比选思路,为大跨度桥型方案比选提供借鉴和参考。 The Ma’anshan Yangtze River Highway Bridge adopts a rare multi-tower suspension bridge scheme at home and abroad. It is the first bridge scheme proposed in China. Its span currently ranks first in the world with the Taizhou Yangtze River Highway Bridge. After nearly 5 years of data collection and preliminary studies, the bridge project was finally successfully implemented. This article introduces the selection principle and design ideas of the pre-bridge type of the Ma’anshan Bridge, and provides reference and reference for the comparison and selection of the long-span bridge type.
