Abstract: The prototype data of hydraulic structures can describe the actual operation situation. However, the effect factors are so complicated that it's difficult to apply the physical methods and mathematic methods to describe the synthetic action between them. The application of fuzzy mathematics in hydraulic structures provides an effective method to deal with these problems. In this paper, clustering analysis, pattern recognition, likelihood reasoning and fuzzy comprehensive evaluation were discussed respectively.

摘要： 原型观测资料真实反映了建筑物观测物理量的实际情况，但其间关系极为复杂，往往难以用物理力学方法和先进的数值计算方法来确定。应用模糊数学原理，可以对建筑物原型观测数据资料进行模糊分析，从而得到较精确的结果。本文分别就聚类分析法、模糊识别、似然推理法和综合评判法进行介绍。
