城市暴雨强度公式的探索

In this paper,some problems such as complicated calculation and unreasonable samplingmethod existing in formulation of current urban rainstorm intensity formula were analyzed in this paper，in order to improve the design of the accuracy of storm intensity in city, made the establishment of urban design storm intensity to explore some of the information technology methods.setting up the applicable, accurate and reasonable formula storm intensity will have a direct bearing on the investment and safe operation of engineering construction of urban rainwater drainage systems. for the existing urban storm intensity formula, analysis of a number of issues of the sample selection, as well as the return period of conversion applications in geographical reasons as so on,and Choose the right formula for storm intensity.
