摘　　要：抽水蓄能电站项目扰动地表面积大,土石方挖填数量大,产生弃渣量大,通常设置的弃渣场规模等级较高,因此弃渣场的规划设计是水土保持工作的重点和难点。根据国家水利部最新文件及相关标准规范要求,以陕西曹坪抽水蓄能电站下库弃渣场为例,结合渣场自然条件分析探讨弃渣场选址、堆置方案选择、排洪方案比选及水土保持措施设计,结果可为同类型工程提供借鉴。Pumped storage power station projects disturb a large surface area,involve a large amount of earthwork excavation and filling,and produce a large amount of waste slag.The waste slag sites are usually of a high scale,so the planning and design of waste slag sites are the focus and difficulty of soil and water conservation.According to the latest documents of the Ministry of Water Resources and relevant standards and specifications,this paper takes the waste slag site of the lower reservoir of Caoping Pumped Storage Power Station in Shaanxi as an example,and discusses the site selection,stacking scheme selection,flood discharge scheme comparison and soil and water conservation measures design in combination with the analysis of the natural conditions of the slag site.The results can provide reference for similar projects.
