摘要
本文依据61年长系列水文实测整编资料,首先采用水文比拟法对资料进行了断面一致性计算分析;然后采用P-Ⅲ频率曲线适线法对大汶口(临汶)站年径流量进行了分析,掌握了丰、平、枯水年的分布规律;对洪峰流量进行了统计分析,分析出不同保证率下的洪峰流量;分析了洪水组成及特性,为水文勘测、预报、防汛提供科学依据。
First of all, the article calculates and analyzes the consistency of the fracture surface by using hydrological analogy method, the analyzes based on the hydrologic measured records which has 61 older series; then the article analysis the annual runoff of Da wen kou(Lin Wen) station by using the P-Ⅲ frequency curve fitting method, and mastered the distribution of wet, normal and dry years; the peak flow was analyzed and the analyzes got the peak flow under different guarantee rates; the composition and characteristics of flood are analyzed, which can provide scientific basis for hydrological survey, forecast and flood control.
