Negative Angle Vertical Rotating Construction Method of Reinforced Concrete Arch Bridge

Abstract

The construction method is a key technical factor to determine whether a concrete arch bridge design is reasonable and applicable. In most mountain areas of western China, a new construction method is being applied in concrete arch bridge construction in order to meet the challenge of severe construction condition, inconvenient transportation and high construction expenses. Pearl Bridge is the first to adopt the negative angle vertical rotating construction method in China. This paper takes Pearl Bridge as an example to introduce the construction process of this new method and discusses its key procedure and constructional details.
