| 摘 要： | 针对大跨度钢管混凝土拱桥安全性评价模型,通过层次分析法建立评价模式,运用MATLAB软件计算出基于指数标度法的判断矩阵的分层次权重,得出拱桥的承载沉降与位移、主拱肋挠度、冲击系数等因素对拱桥安全性的影响较大,这与专家评估结果相吻合.表明基于MATLAB的层次分析法在拱桥安全性评价中的有效性和实用性.

| Abstract: | Aiming at the safety evaluation model of long-span CFST arch bridge, the paper established evaluation model based on AHP and applied MATLAB software to figure out the judgment matrix of hierarchical weight based on exponential scale method. Therefore, it was consistent with the expert evaluation results that some indexes greatly influenced the safety of large bridge, such as the load bearing settlement and displacement, the main arch rib deflection, the impact coefficient. The results show that the effectiveness and practicability of the AHP in arch bridge safety assessment based on MATLAB. |
