Study of the Additional Anti-Corrosion Measures of Bridge Pier Caps Concrete in Beijing-Shanghai High Speed Railway

Abstract

Based on the analysis of corrosion mechanism, combining with the characteristics of bridge structure, aiming at the existence of corrosive medium and complex physical environment, such as the freezing thawing, corrosion and chlorine salt as well as dry wet, freeze-thaw cycle [, This paper expounds the research and construction practice of the additional anti-corrosion measures of bridge pier caps concrete in Beijing-shanghai high speed railway. It has a certain guiding significance to the similar Bridges in corrosion protection construction.
