摘要:

为有效预防桥梁施工过程中风险事故的发生,给予工程安全前瞻性建议,提出了一种基于云模型改进层次分析法(analytic hierarchy process, AHP)的桥梁施工风险评估方法.首先,利用鱼骨图识别风险因素,构建桥梁施工风险评估体系.其次,考虑赋权过程中专家意见的不确定性,利用云模型改进AHP,计算各指标权重.最后,从风险发生概率和风险造成损失2个维度,构建二维云模型评价各风险因素,结合指标权重计算二维综合云模型,通过贴近度定量描述桥梁施工风险等级.应用上述评估方法对长春某桥梁施工风险进行评估,结果表明,该方法具有较高的可行性和有效性,能够为桥梁施工风险的预防和控制提供借鉴和参考.

Abstract:

In order to effectively prevent the occurrence of risk accidents during bridge construction and give prospective suggestions for engineering safety,a bridge construction risk assessment method based on cloud model improved analytic hierarchy process(AHP) was proposed. Firstly,the fishbone diagram was used to identify risk factors and construct a bridge construction risk assessment system. Secondly,considering the uncertainty of expert opinions in the process of assigning weights, the cloud model improved AHP is used to calculate the weights of each index. Finally,the two-dimensional cloud model is constructed to evaluate each risk factor from two dimensions: the probability of risk occurrence and the loss caused by risk. Combined with the index weights,the two-dimensional comprehensive cloud model was calculated to quantitatively describe the bridge construction risk level through the close degree. The above assessment method was applied to evaluate the construction risk of a bridge in Changchun. The result shows that the method has high feasibility and effectiveness,and can provide insights and references for the prevention and control of bridge construction risk.

Key words: bridge construction, risk assessment, cloud model improved AHP, two-dimensional cloud model
