超大洪量的山谷干式贮灰场排洪系统设计方法

Analysis on the Design Method of Drainage and Flood Discharge Structure of Dry Ash Disposal Area in Valley with Super Large Peak Discharge

贮灰场排洪系统是贮灰场的重要设施,尤其对于超大洪峰流量、沟谷河流型的山谷干式贮灰场,其排洪系统是设计环节的重中之重,是防止贮灰场发生溃坝和泥石流的关键因素。通过西南地区某电厂干式贮灰场排洪系统设计的分析和总结,提出超大洪量的山谷干式贮灰场排洪系统设计方法,为今后超大洪量的山谷型干式贮灰场排洪系统设计提供思路。

The drainage and flood discharge structure is an important facility for the ash disposal area.Especially for dry ash disposal area in valley with super large peak discharge,the drainage and flood discharge structure is the most important part in the design process,it's the key factor to prevent dam break and debris flow.Based on the analysis of the drainage and flood discharge structure design of a fossil-fired power plant’s dry ash disposal area in Southwest China,this paper proposes the design method of dry ash disposal area in valley with super large peak discharge,which provides ideas for designing drainage and flood discharge structure of dry ash disposal area in valley with super large peak discharge.
