摘　　要：针对评价指标标准值与评分值为模糊数的综合评估问题,将模糊数引入灰关联综合评估领域,提出了一种基于模糊数平面距离的多指标多层次灰关联综合评估方法.为了评估现场扣件式钢管支模架的施工风险,设计了一套多指标多层次的扣件式钢管支模架的施工风险评估系统.通过10个工程的问卷调查,确定了系统各评价指标的权重和评分值.借助于该评估方法,建立了扣件式钢管支模架施工风险评估体系.最后实例分析表明该方法和评估系统的正确性和有效性.To study comprehensive evaluation problems in which criteria values and marks are fuzzy numbers, fuzzy numbers are introduced into grey relational comprehensive evaluation field, then a new multi-level and multi-attribute grey relational comprehensive evaluation method based on plane distance between fuzzy numbers is proposed. To evaluate the safety of fastener-style tubular steel formwork-support （FTSF） in project management, a safety assessment of multi-level and multi-attribute system was established on the basis of consultation with a number of FTSF experts. After investigation in 10 construction sites in terms of questionnaire, the weight and mark of each index in the system was brought out. Utilizing the new method, a system of construction safety appraisal for FTSF is presented. Finally an application shows the correctness and effectiveness of the proposed method and the assessment system for FTSF.
