The Construction of the Main Bridge of the Yichang Yangtze River Railway Bridge in China

Abstract

Railway construction technology in China, especially of high-speed railway long-span bridge construction, has been developing rapidly since the beginning of the twenty-first century. To maintain the dynamic characteristics, travel safety and passenger comfort when the train travels over a bridge at high speed, and, at the same time, to meet the requirement of economical and technical viability of construction of the bridge—was a challenging problem. For solving this problem, many new types of bridge structure have been developed for railway and high-speed railway long-span bridges. The arch beam hybrid structure is one of the structures that have been widely used in China. It is normally made up of a prestressed concrete (PC) beam, a rigid frame, or V-shaped piers and a steel arch or concrete-filled steel tube arch.
