枕头坝一级水电站渣场规划设计

Planning and design for spoil ground of Zhentouba Hydropower Station Ⅰ

江沟渣场是枕头坝一级水电站唯一的堆料弃渣场。通过对工程开挖料、有用料及无用料的土石方平衡调运分析,确定了该渣场的容量。结合现有地形条件,本着方便渣场施工和有用料回采利用的原则,对渣场进行了整体规划,将渣场划分为5个区域。对堆筑体的稳定性和排水等进行了细致设计,取得了良好效果。对类似工程有参考价值。

Jianggou spoil ground is the only gravel spoil ground of Zhentouba Hydropower Station I. We conduct a balance and transportation analysis on the excavated material, usable material and useless material to determine the capacity of the spoil ground. Based on present geography and for the sake of being convenient for spoil ground construction and utilization of excavated material, we divide the spoil ground into 5 zones. The stability design of deposit body and slope drainage is discussed in detail with satisfying effects.
