Risk factors analysis and risk assessment of sudden pollution from traffic accidents in the Middle Route of South-to-North Water Diversion Project

摘要：

　　The traffic bridges along the route of South-to-North Water Diversion Project are numerous.Once a traffic accident occurs causing pollutants in the channel,the water safety,ecological environment and economic development of water receiving areas along the line will be affected.We investigate the bridges along the channel,focusing on the investigation and analysis of hazardous chemicals,nearby backwater gates and water inlets involving 173 cross-channel bridges with large traffic volume.The risk evaluation index system of sudden water pollution is established in this study,while the risk of different bridges is evaluated.We divide bridges in three risk grades,and delimit key prevention areas and key monitoring objects.And the stress of traffic risk factors on the water quality safety is summarized.It is significant for being regarded as basis for contingency plans,hierarchical responses and emergency material reserve for the middle line of the south-to-north water diversion project.
