The towers of the Yangmeizhou Bridge is a single-pillar shape and its height is 181m, which is the highest building in Xiangtan City. This research focuses on several significant problems during construction, including how to prevent bored pile hole collapse when excavating large karst caves, how to improve piling efficiency of composite piles when excavating cobbles, how to assemble a large-diameter and double-wall steel cofferdam in deep water, how to control the temperature of mass concrete in summer, how to apply climbing formwork according to variable sections of towers, and how to install cable ducts and steel anchor beams with high precision. These findings provide a key guide and reference for similar bridge engineering projects.
