| 中文摘要: |
| 结合水工闸门工作特点，通过对全国81座大型水库门前年峰水位的统计分析，阐明了门前峰水位(年水头峰值)基本服从于正态分布，对数正态分布和极值Ⅰ型分布，且其概率分布特征不同于坝前峰水位的分布特征；并在此基础上，进一步给出设计基准期内门前峰水位的概率分布函数和特征参数.可供水工闸门可靠度设计及有关荷载规范制定时参考. |
| 英文摘要: |
| The statistic of 81 water projects indicates that the probability of annual maximum water level acting on gates obeys the normal distribution, log-normal distribution and Gumbel distribution, and the characteristic parameters are different from those of annual maximum water level of reservoirs. On this basis, the probability distribution function and relevant characteristic parameters of annual maximum water level acting on gates within the life expectancy are deduced. |
