我国西南地区由于山高坡陡,建设过程中产生了大量的弃土、石、渣(后简称弃渣),这些弃渣如得不到较好的处理将造成严重的水土流失,弃渣处理正慢慢成为水保和环评验收中的制约性因素之一。因此,开发建设项目应充分重视渣场的有效处理。着重探讨西南高山区中小水电开发临河(沟)型渣场的工程措施,包括拦渣堤、排水沟等的设计简化过程。 Due to the steep hillsides in the southwestern region of our country, a large amount of spoil, stone and slag (hereinafter referred to as spoil) are produced in the process of construction. These spoils can cause serious soil erosion if they are not properly treated. Slowly become one of the restrictive factors in the acceptance of water conservancy and environmental impact assessment. Therefore, development and construction projects should give full attention to the effective treatment of slag yard. This paper focuses on the engineering measures for the development of Linhe ditches in small and medium-sized hydropower stations in southwest high mountainous areas, including the design simplification of dregs and drainage ditches.
