以渡槽结构综合状态为总目标,建立以安全性、耐久性和适用性为子目标的评估模型.采用不确定型层次分析法(AHP)对渡槽结构进行状态评估,首先构造以区间数表示的不确定型判断矩阵,采用最小二乘法计算指标权重,然后根据专家对底层指标的缺损状况给出的扣分值,逐层计算上级从属指标的状态分值,进而确定渡槽的结构状态,从定性或定量的分析给出了渡槽各指标的评估标准.
Based on the comprehensive status of aqueduct structure, an assessment model with safety, durability and applicability as sub-goals was established.Uncertainty analytic hierarchy process (AHP) was used to assess the aqueduct status, Uncertainty judgment matrix, using the least squares method to calculate the index weight, and then according to experts on the underlying indicators of the defect status given deduction, layer by layer to calculate the subordinate indicators of state scores, and then determine the aqueduct structure state, from the qualitative Or quantitative analysis of the indicators of the aqueduct evaluation criteria.
