摘要
根据实测断面资料计算了洪水调查痕迹相应洪峰流量,采用概率统计的方法分析场次大洪水洪峰比,以年最大洪峰流量模比系数综合频率曲线法推求小流域的设计洪水,并以实地调查及推理公式法验证了计算结果的相对合理性,为新疆冲洪积扇区域小流域洪水的计算提供了一条新的途径。
According to measured section data , the paper calculated flood peak flow which reflects the trace of flood investigation and used the method of probability and statistics to analyze the ratio of screen-ing large flood peak .It used the comprehensive frequency curve of mode ratio of annual maximum peak flow to derive the design flood of small watershed and verify the relative reasonableness of calculation method .The method can provide a new way for the calculation of small watershed flood in Xinjiang alluvi-al fan area .
