This present book mainly introduces the latest advancements in design and construction technologies of large-span concrete-filled steel tubular (CFST) arch bridges and steel-reinforced concrete (SRC) arch bridges with a CFST rigid skeleton. The main contents include overall introduction, structural design of the 500-meter scale CFST arch bridges, manufacture and transportation of the steel arch truss segments, design and construction of the buckling system of stayed cables, calculation method and its practice for one-time tensioning of buckle cables, preparation and pouring of the in-tube concrete, design, construction and application of the hoisting system of suspension cables, active force method for displacement control of the hoisting and buckling tower, and the state of the art of the SRC arch bridges. The major innovations of the book are generally summarized from the engineering practices of three recently built super-large-span CFST arch bridges in China, which were guided by the author and his team. Therefore, the well-organized book is of both high practical and theoretical value.
This book is a good reference for bridge design and construction professionals. Also, it serves as a textbook for undergraduate students majoring in civil engineering and graduate students majoring in structural engineering, bridge and tunnel engineering in universities.

Prof. Zheng Jielian is the academician of Chinese Academy of Engineering (CAE) and a world-renowned specialist in bridge engineering. He has long been engaged in the field of bridge design, construction and management (especially in arch bridges). His main professional achievements include pioneered the non-bracket construction method of double-curved arch bridge in China, which has solved the historic technical conundrum of constructing arch bridges without bottom supports; proposed the regulation method for the instantaneous and permanent stresses in steel rigid skeleton of large-span steel-reinforced concrete (SRC) arch bridges when pouring the concrete encasement. He is also the chief consultant of both the longest (in main span) concrete-filled steel tubular (CFST) arch bridge and SRC arch bridge in the world. Thus, he is well-recognized to have made great contributions to the high-quality and high-speed development of CFST and SRC arch bridges in China and to the leading positionof China on these two types of bridges. His research and service have garnered a lot of awards from the government and professional organizations, including three National Science and Technology Progress Award of China and the Li Guohao Bridge Original Technology Award.
