摘要
首先给出模糊数学在拱坝安全评价中的应用方法和步骤,然后在拱坝体型设计统计模型的基础上建立了考虑厚高比、柔度和最大拉应力3个因素的模糊综合评价模型,并对数座拱坝进行了验证.验证结果表明,拱坝模糊综合评判方法简便易行,评判结果切合实际.
An introduction is given to the method and steps of fuzzy mathematics applied to safety evaluation of arch dams, and a fuzzy comprehensive evaluation model, with the thickness-height ratio, flexibility, and the maximal tensile stress of arch dams taken into account, is established based on the statistical model for shape type design of arch dams. The model is applied to safety evaluation of several arch dams, and the results show that the model is easy to use, and the evaluated results are in good accordance with the reality.
