岷江上游水电工程临河型弃渣场水土流失量预测研究

Study on soil and water losses prediction in waste disposal area close to river in hydro-power project of upper reaches of Minjiang River

摘要: 根据2006年7月对岷江上游部分水电站弃渣场的调查,统计分析各渣场现有堆渣量与设计堆渣量的差值,从而得出各渣场流失量与堆渣量的比值,即为流弃比;分析流弃比产生的原因和组成,提出岷江上游地区以石料为主的临河型渣场流弃比取值范围,为以后该地区和其他类似地区的同类型渣场的水土流失预测提供参考。

Abstract: The paper has calculated the real and design waste disposal amounts according to the survey of some hydro-power station in the upper reaches of Mingjiang River in July,2006,and got a loss to disposal ratio(LDR),that is,the ratio of loss to disposal in every waste disposal area.The reason and formation of LDR are studied.The reasonable scopes of LDR are proposed in the waste disposal area close to the upper reaches of Mingjiang River for stone tiles and slabs for providing references of soil and water losses prediction to the areas in the near future and similar areas.
