Abstract
Located in high seismic intensity region, the viaduct of Line Daxing in Beijing Rail Transit has a total length of 3. 167 kilometers, with many control points leading to complicated design conditions. According to urban viaduct design features in high intensity seismic region, this paper introduces the project profile and the main technical standards. Then, the design principles of span arrangement and bridge style of the viaduct are summarized, while the rapid construction measures for standard girder of the viaduct are proposed. This paper also analyzes the key factors of section sizes and types of the piers. Finally, the paper describes the seismic design principles, seismic response spectrum, ductile design methods of the reinforced concrete piers of the viaduct, and then puts forward a number of measures to deal with important issues in the design.关键词
