摘　要:

研究了将模糊规则推理和粗糙集理论相结合建立大坝安全监测变形预测模型的新方法。该方法采用粗糙集理论对原始监测样本数据进行离散,根据离散结果确定模糊推理规则,并通过对规则的模糊推理建立大坝安全监测变形预测模型。实例分析表明,该模型在大坝变形影响因素重要性评价和非确定性测值预测方面取得了满意的结果。

Abstract:

A new deformation prediction method which combines the fuzzy inference and rough set is put forward. Based on the rough set the observation data is discretized. According to the diseretization result, the fuzzy inference rule is determined and an accurate prediction model for dam deformation is established.
