     Based on the characteristics and distribution of quicksand in Shanghai, this paper presented an index system for quicksand risk assessment, aiming of risk assessment, zoning and management division of quicksand. First, according to the spatial distribution characteristics of ②3, ⑤2 and ⑦ silty-sandy soil layers, the danger anal- ysis and zoning of quicksand are carried out. Second, based on administrative division and comprehensive consider- ation of socio-economic statistical indicators, the vulnerability analysis and zoning of quicksand are made. And on that basis, the risk comprehensive evaluation and division are conducted. Finally, risk control and management zon- ing of quicksand during the 12th five-year planning are presented by combining the content on economic and urban key projects of outline of the 12th five-year planning for economic and social development of Shanghai. The results of this paper can provide guidance and geological basis for possible quicksand＇s monitoring, prediction and preventionduring underground construction （excavation, subway tunnels, underground supermarket, etc. ）, including investi- gation, design, construction, and provide decision-making reference for management departments.
