摘要
运用模糊数学的理论,对泄洪水雾的预报问题进行了研究。在分析和给出影响泄洪溅水量的主要特征因子及其隶属函数的基础上,由若干原观资料,建立了泄洪溅水特征因子的模糊关系矩阵。利用该矩阵和模糊线性加权变换,求出各影响因子的加权系数和归类阈值界限,从而建立了预报泄洪溅水的综合评判模式。本模式的预报结果与原型实测成果符合较好。
It is very important to predict the influence of overflow spray-motion on hydraulic power project at downstream of high-head dam. In this paper, by applying the fuzzy mathematical theory the prediction model for overflow spray-motion is investigated . Based on the analyses of main characteristic factors which affect the overflow spray-motion and their membership functions, the fuzzy relation matrix from the field data is established .According to the fuzzy linear weighting transformation programming and the relation matrix, the weighting coefficients for various characteristic factors and threshold values for aggregation are obtained , and the synthesis decision model for predicting overflow spray-motion is defined. It is demonstrated that the predicting results are in agreement with the field observations
