摘　　要：为有效控制拓宽路堤高边坡施工风险,基于模糊物元分析法提出一种施工安全评估模型。首先,针对拓宽路堤施工的工程特点,构建包括4个一级指标(诱发因素、交通组织、施工环境、施工设计)和11个二级指标(施工季节、自然灾害影响、交通量、交通布控与导改、施工周边环境、原边坡变形、填方高度、地基处理、加固方式、设计资料完整性、施工机械)的安全风险评估指标体系。其次,采用层次分析法和熵权法(EWM)分别计算一级和二级指标的权重。最后,运用模糊物元分析法构建拓宽路堤施工安全风险评估模型,并将其应用于实际工程当中,通过对比验证了模型的有效性。结果表明:该模型能够有效评估拓宽路堤高边坡施工的整体安全风险。In order to effectively control the construction risk of widening embankment high slope,this work proposed a construction safety assessment model based on fuzzy object element analysis.Firstly,for the engineering characteristics of widening embankment construction,a safety risk assessment index system including 4 first-level indicators(triggering factors,traffic organization,construction environment,construction design)and 11 second-level indicators(construction season,natural disaster impact,traffic volume,traffic control and guided change,construction surrounding environment,deformation of the original slope,fill height,foundation treatment,reinforcement method,completeness of design data,construction machinery)is constructed.Secondly,hierarchical analysis and entropy weight method(EWM)were used to calculate the weights of primary and secondary indicators respectively.Finally,a safety risk assessment model for widening embankment construction was constructed by using fuzzy object element analysis,and it was then applied to actual engineering examples to verify the effectiveness of the model through comparison.The results show that the model can effectively assess the overall safety risk of widening embankment high slope construction.
