摘要

随着我国桥梁结构形式的不断创新、桥梁施工难度不断增加以及施工过程中不确定因素的增多,加强对桥梁施工过程安全风险评估对于保证工程的顺利进行尤为重要。以某双塔钢桁梁结合梁斜拉桥为工程依托,基于FAHP分析方法建立了施工过程风险评估模型,并对该桥梁施工过程安全进行风险评估。研究成果如下:基于加权平均法构建了可用于桥梁施工安全风险评估的模糊层次分析法(FAHP);基于FAHP建立桥梁施工风险评估模型对各影响因素和整体风险进行评估,确定各因素风险级别并进一步用于确定桥梁施工安全最不利影响因素,为合理采取风险控制措施提供依据; FAHP安全风险评估法在钢桁梁斜拉桥施工安全风险评估中的顺利实施可为其他工程提供参考。
        With the continuous innovation of bridge structure,the increasing difficulty of bridge construction and the increasing uncertainties in the construction process,it is particularly important to strengthen the safety risk assessment of bridge construction process to ensure the smooth progress of the project.Based on the FAHP analysis method,this paper establishes a risk assessment model for the construction process of a cable-stayed bridge with double-tower steel truss and composite girder,and carries out a risk assessment for the safety of the bridge construction process.The main research results of this paper are as follows:Based on the weighted average method,a fuzzy analytic hierarchy process(FAHP) for bridge construction safety risk assessment is constructed;based on FAHP,a bridge construction risk assessment model is established to evaluate the influencing factors and overall risk,determine the risk level of each factor and further determine the bridge construction.The most disadvantageous factors of construction safety provide the basis for the reasonable adoption of risk control measures.The successful implementation of FAHP safety risk assessment method in construction safety risk assessment of steel truss cable-stayed bridge can provide reference for other projects.
