Based on fuzzy characteristics in durability failure criterion of concrete structures durable life was estimated , in which process survival analysis method was considered with fuzzy theory and the contribution of statement of truncation data was taken into account 结合混凝土结构在耐久性评价中包含许多模糊性因素的特点,将模糊数学的思想融入到生存分析法中。基于结构的耐久性失效准则,并考虑删失数据的状态对混凝土结构耐久寿命的贡献,对混凝土结构的耐久寿命进行了统计分析。
Based on the uncertainty and fuzzy characteristic of occurring of piping , fuzzy neural network of piping is proposed further . the same collected data is used to train and predict the model and gets good results , which proves fuzzy artificial network is also an effective method to predict and judge the occurring of piping 针对管涌发生的不确定性和模糊性,文中进一步建立了管涌的模糊神经网络模型,用同样的样本对模糊神经网络进行训练和测试,获得不错的预测结果,证明模糊神经网络也是预测判定管涌发生的有效方法。
