摘要
以斜拉桥的基本组成与施工期人员队伍的设置为基础,对斜拉桥施工风险因素识别和筛选,构建斜拉桥施工风险评估体系。首先采用层次分析法计算施工期风险因素权重值,再以灰色模糊数学理论进行斜拉桥施工期风险综合评价,最终根据评价指标及结果,提出斜拉桥施工防控措施。层次分析法与模糊数学理论的结合,较准确、全面地得出斜拉桥施工风险总体水平,为斜拉桥建设期间的质量安全管理与施工风险控制提供有益参考。
Taking the basic composition of cable-stayed bridge and the setup of construction team as the basis,this paper identifies and screens the construction risk factors of cable-stayed bridge to build the construction risk assessment system of cable-stayed bridge.Firstly,the analytic hierarchy process is adopted to calculate the weighted value of risk factors in the construction period,then the gray fuzzy mathematic theory is used to carry out the comprehensive assessment of risk in the construction period of cable-stayed bridge,and finally based on the assessment indexes and results,the prevention and control measures for the construction of cable-stayed bridge is proposed.The combination of analytic hierarchy process and fuzzy mathematic theory can more accurately and comprehensively obtain the overall level of construction risk of cable-stayed bridge,which can provide the beneficial reference for the quality safety management and the construction risk control in the construction period of cable-stayed bridge.
