Foundation design of single-span arch bridges in China

Arch bridges have been constructed in China more than 1400 years ago. This study collated the details of 120 single-span arch bridges with spans of more than 100 m that have been constructed or undergoing construction in China over the recent three decades. The type proportion, span to rise ratio, spatial distribution, and span length of the 120 arch bridges were reported in this paper. An examination of the foundation of the 120 single-span arch bridges was further conducted. Based on the analysis of the arch bridge foundations, it was found that the foundation types can be grouped into enlarged footing, pile foundation, composite foundation, and “others”. Thus, the application rate of various foundation types, characteristics of each foundation type, and development trend of arch bridge foundations were investigated and discussed. Finally, case studies of single-span arch bridge with composite foundations consisting of open caisson and shaft, and foundation with barrette piles were reviewed. The construction techniques, applicable conditions and resistance characteristics of various foundations were analyzed and evaluated. The case studies highlighted in this paper illustrated the advancement, innovation and development in foundation engineering of single-span arch bridges in China.
