摘　　要：对九江长江公路大桥桥塔施工全过程中可能影响施工质量、施工安全和施工进度的各种不利因素进行风险评估,并对其中桥塔建设期间爬模系统和桥塔自身抗风问题进行详细的风险分析,由此对各风险事态提出建设性的风险控制措施,编写了风险管理手册,结合风险评估报告整合形成整体的风险管理系统,指导具体的施工过程,研究成果在九江长江公路大桥桥塔施工过程中得到应用。The risks of various adverse factors are assessed which may have influence on the construction quality,safety and progress of the whole construction process of the pylon of Jiujiang Yangtze River Highway Bridge(Jiujiang Bridge).The climbing formwork system and the pylon,which are primary focused,are computed on wind resistance in the construction stage.Accordingly,the suggestive control measures against the various risk events are put forward,and the risk management handbook is given.As a result,a set of the complete risk management system for the pylon is finally formed for guidance of the specific construction.The research results presented in the paper were successfully used in the construction of the pylon of Jiujiang Bridge.
