芜湖长江公路二桥新型锚索系统方案研究

Research on a new anchor cable system for Wuhu Yangtze River highway bridge

介绍了一种应用于大跨径柱式塔斜拉桥的新型锚索系统。通过对斜拉桥各类锚索系统进行调研,结合芜湖二桥的实际情况,选取可行的锚索方式,并进行综合的技术安全性与经济性比选,确定合理的锚索系统,为设计人员在大跨径斜拉桥总体设计及锚索系统的选型提供了依据,也为今后同类斜拉桥的设计提供了新的思路。

This paper introduces a new anchor cable system applied to long-span column pylon cable stayed bridge. Through the investigation of all kinds of cable system of cable-stayed bridge, combined with the actual situation of Wuhu Yangtze River highway bridge, the feasible anchorage cable mode is selected, and the comprehensive technical safety and economy and comparison are carried out to determine the reasonable anchor cable system, which provides the basis for the designers to select the overall design of the long-span cable-stayed bridge and the selection of the anchor cable system. It provides a new idea for the design of similar cable-stayed bridges in the future.
