Railway Automation Monitoring of Wufengshan Bridge

Project Overview

The newly built railway Lianyungang-Zhenjiang line is located in the eastern coastal area of my country, on the longitudinal central axis of the north-central Jiangsu Province. The line starts from Lianyungang City in the north, leads to Huai'an City along the Ninglian Expressway, runs parallel to the Beijing-Hangzhou Canal and the Beijing-Shanghai Expressway, passes through Yangzhou City in the south, and ends in Zhenjiang City after crossing the Yangtze River. It runs from north to south, with a total length of 304.883km. The Wufengshan Yangtze River Bridge on the Lianzhen Railway is the world's first high-speed railway suspension bridge and China's first dual-use highway-railway suspension bridge.

The bridge is the controlling project of Lianzhen Railway and also the most difficult project to construct on the entire line. The main bridge of Wufengshan Yangtze River Bridge is located in a straight line, with the main span as the center of symmetry and a 3‰ herringbone longitudinal slope. Static level sensors are used to observe the vertical displacement of CPIII control points, thereby realizing real-time automatic vertical deformation monitoring of the track control network (CPⅢ) within the main span of the main cross-river bridge.
