水闸上游水位变化规律统计分析

STATISTICAL ANALYZE OF SLUICE IN UPRIVER WATER LEVEL VARIATIONAL RULE

收集淮河流域、太湖流域主要大中型水闸历年最高水位资料 ,用KS法对上述水位的分布规律进行分布拟合假设检验 ,其结果为 :水闸内河侧水位变化规律不拒绝正态分布、对数正态分布 ,但正态分布最优 ;水闸沿江、沿海侧潮位的变化规律不拒绝正态分布、对数正态分布和极值I型分布 ,但极值I型分布最优 .此结果可为水闸可靠度设计和《水闸设计规范》的修订提供一定依据 .

This paper collects the data of past years tiptop of the large\|middling size sluice in Huaihe and Taihu valley. This data is supposed proven for stat distributing rule using the KS way. The results show that the water level variation in freshwater side doesn′t refuse normal school and logarithm normal school, but coincides with normal school better. Along Yangtze river and Yellow sea side it doesn′t refuse normal school, logarithm normal school, and extremum I distributing, but coincides with extremum I distributing best. The conclusion can provide scientific basis for sluice reliability design and recension 'The Standard of Design Sluice'.
