大跨径连续梁桥施工阶段风险因素探析

Discussion and Analysis on Risk Factor at the Construction Stage of Large-span Continuous Girder Bridge

首先对桥梁结构施工过程中的风险源进行识别,分析了大跨径连续梁桥施工阶段的风险因素,分别从基础施工、主梁施工两方面归纳连续梁桥施工中具有的风险因素,再从人为风险、技术风险、自然风险三方面提出了相应的控制措施,最后以某大桥工程实际案例入手进行了具体分析。

The identification of risk source during the bridge structure construction is made firstly,the analysis on risk factor at the construction stage of large-span continuous girder bridge is made,the risk factor during the construction of continuous girder bridge is respectively summarized from two aspects like foundation construction,main girder construction,and then corresponding control measures are put forward from three aspects like human risk,technical risk and natural risk,and the analysis is made concretely at last by starting from the actual case of a bridge engineering.
