摘　　要：为对高大模板扣件钢管支撑专项施工方案的安全可靠性进行客观的评价,提出了采用层次分析法确定高大模板扣件钢管支撑专项施工方案的可靠性评价指标,并构造出相应的层次结构模型。经过比较、建立判断矩阵,计算矩阵特征向量和最大特征值。根据综合计算,并对相对权重进行总排序,然后用二级模糊评判技术进行模糊评价的方法。该方法的评价结果,较为客观全面地反映高大模板扣件钢管支撑专项施工方案的可靠性状况。For objective safety evaluation of high-formwork support scheme for fastener-style steel pipes, hierarchy analysis method was adopted to ascertain its reliability evaluation indexes. Corresponding structure model was constructed and judgment matrix was formulated. The eigenveetors of matrices and maximum eigenvalue were calculated. Relative weight sequencing was performed and two-level fuzzy assessment was conducted. The result shows that the method can objectively assess the safety of the construction and management of high formwork support for fastener-style steel pipes.
