The environmental effects and zoning for the durability performance of concrete bridges were systematically studied. First, the major influence factors for concrete bridges in different places were investigated according to the environmental effects and the durability diseases. Then, the environmental indicators which had significant impact on durability performance of concrete bridges were investigated and analyzed on the basis of meteorological information data from the National Meteorological Center (NMC). Subsequently, proper environmental parameters were chosen in order to classify the environmental conditions of concrete bridges by the current design codes and standards. Finally, the environmental zoning maps and tables for different environmental parameters were obtained by the ArcGIS software.
