Exploring of the particularity of waterlogging risk assessment standards for civil airports:Based on the risk assessment of waterlogging at Guangzhou Baiyun International Airport
Civil airports cover a wide area and have complex land attributes,areas such as ter-minal areas,work areas,and freight areas,as well as areas such as flight zones that are completely different from cities in terms of construction and management.The application of urban waterlog-ging evaluation standards to civil airports often has certain mismatches.Guangzhou Baiyun Interna-tional Airport covers a total area of 35 square kilometers,with high rainfall,single peak and con-centrated rainfall patterns,and complex surrounding hydrological conditions.After the completion of this phase,a total of 5 runways and 2 terminal areas will be established,ranking among the most complex hub airports in China,which is highly typical.Based on the waterlogging risk as-sessment work of the this phase,in-depth discussions were conducted on the problems exposed during the waterlogging risk assessment process of civil airports and the similarities and differences with urban waterlogging assessment standards.
