山谷型火电厂贮灰场设计洪水计算

摘要

电力工程中山谷型的贮灰场流域常常缺乏充分的实测雨洪资料，广泛运用水科院推理公式法推求设计洪水，具有一定实用性，本文以四川某一山谷型电厂贮灰场为例，结合当地区流域情况，主要采用推理公式法计算贮灰场设计洪水，在电力行业特小流域设计洪水计算方面具有参考价值。%In the valley-type ash storage basin of power engineering,there is often a lack of suffi-cient measured data of rainfall and flood.The widely used IWHR reasoning formula has certain practicability.An ash storage place of a valley-type power plant in Sichuan being taken as an ex-ample and combined with the conditions of the local river basin,reasoning formula method is mainly adopted to calculate the design flood of an ash storage place,which has reference value for design flood calculation of small watershed in electric power industry.
