摘要
根据2001年日到船资料的统计分析,施桥船闸到船量具有随机性.上、下行船的到船不均衡系数也不同.若采用全部船舶到船资料分析到船不均衡性时,需用差异系数对分析结果进行修正.引入的时间保证率能表征日到船量偏离平均情况的程度,时间保证率越高,到船的不均衡性越大.
The ship arriving at Shiqiao Lock is random according to the statistic analysis of the data in 2001. Values of the uneven coefficient are different between upward ships and downward ships. The analytical results should be modified by a difference coefficient when the uneven character analysis is based on all the arriving ships. A time guarantee percentage is introduced to denote the degree of daily-arriving-ship quantity deviating from the average level. The higher the time guarantee percentage is, the greater the uneven coefficient is.
