In order to cope with the excess runoff that exceeds the source emission reduction and the carrying capacity of rainwater pipes and canals,the dual-use drainage and waterlogging pre-vention system,as an important part of the urban large drainage system,can effectively reduce the urban waterlogging disaster and improve the urban waterlogging resilience.The concept of dual-use drainage and waterlogging prevention is defined,and different types of dual-use drainage and waterlogging prevention facilities and their functions are classified and analyzed in detail.Through the development status of dual-use drainage and waterlogging prevention systems at home and a-broad,the relevant policies and standards are mainly discussed.The shortcomings in the current theory and technical system of dual-use drainage and waterlogging prevention are pointed out,and the theoretical framework of dual-use drainage and waterlogging prevention is sorted out.Com-bined with practical cases at home and abroad,summarize the experience and put forward sugges-tions for the future development of dual-use drainage and waterlogging prevention.
