| 中文摘要: |
| 针对正常运用的坝体上游水深随机变量统计分布类型的判定问题，采用模糊集合论原理建立了该问题的模糊数学分析模型，给出了以马氏距离为判别量的相对模糊识别方法。对77座大中型水库的分析结果表明，本文的方法具有较好的规律性，可以认为，上游水荷载随机变量服从正态分布。 |

| In this paper,an analytical model was put forward ot distinguish the probability distribution of random variable bgy applying fuzzy set theory,aming at solving the problems of the statistical characteristics of water level at the upper dam face.In the method,the M distance was specified as the distinguishing index.In case studies,77 reservoirs were analyzed by the method.The results revealed that the method possesses a good regularity and the hydrostatic load at upper dam face obeyed the law of normal distribution. |
