摘　　要：为研究公路斜拉桥超宽前支点挂篮悬臂浇筑施工的安全风险,以武汉四环线高速汉江特大桥为研究案例,介绍了斜拉桥主梁采用的超宽前支点挂篮悬臂浇筑施工情况,采用系统安全工程的方法对施工过程中可能发生的风险进行分析。根据分析结果,运用LEC评价法,最终确定施工风险防控的重点是坍塌和高处坠落事故。针对风险防控重点,制定了风险控制措施。In order to analyze safety risk of hanging basket with fore fulcra of super-wide cantilever casting construction of highway cable-stayed bridge,Hanjiang Bridge in Wuhan fourth ring highway as an example,the hanging basket with fore fulcra of super-wide cantilever casting construction was introduced.We adopted the system safety engineering method to analyze the possible risk.According to the results of the risk analysis,usingLEC evaluation method,we determined the construction risk prevention and control focused on collapsion and fall accident.Aiming at risk prevention and control focuses,we proposed the corresponding risk control measures.
