应用年最大值法推求城市暴雨强度公式的研究

Feasibility study on deriving the urban storm intensity formula through annual maximum value method

目前采用年最大值法采样的条件日趋成熟。比较了年最大值法与年多个样法推求暴雨强度公式的差别,并通过北京市的实例分析了两种取样方法获得的样本在重现期上存在的关系。在此基础上论述了推行年最大值法取样推求暴雨强度公式存在的问题及建议,提出了该方法在未来应用的可行性,为未来过渡到采用年最大值法选样提供参考依据。

At present,conditions of using annual maximum value method for sampling is becoming more and more mature.This paper compared the difference between annual maximum value method and annual multi-sampling method in deriving storm intensity formula,and analyzed the relationship of return period between samples collected by two different methods in case study in Beijing.Based on this,the problems in application of annual maximum value mtheod in deriving the storm intensity formula were discussed and the related suggetions were offered.The fesibility of the future application of this method was put forward,which offered the references for the future transition to annual maximum value method.
