新疆生产建设兵团农一师四座平原水库渗透稳定研究

Study on the Permeability Stability of the Four Plain Reservoir in Xinjiang Production and Construction Corps,The First Division

渗透破坏是平原区水库大坝发生破坏的主要形式,渗透稳定问题是平原区水库存在的主要问题。在南疆平原区水库除险加固地质勘察过程中,发现水库坝体(基)实际所承受的水力比降远未达到理论计算的允许比降,水库大坝就已发生了渗透破坏,本文以兵团农一师新井子水库、多浪水库、上游水库、胜利水库为列,分坝体、坝体(基)结合处、坝基等不同部位进行研究,提出较合理的临界比降计算方法。

Infiltration is the main damage of the plain reservoir and stability is the main problem. During the plain reservoir is reinforced in southern of Xinjiang,we found that infiltration damage has taken place before the reservoir dam （ base） to bear the actual hydraulic gradient is far from theoretical calculation slope to allow. This paper has put forward a more reasonable method of calculating the critical slope based on the study of the dam,junction and foundation, of Xinjingzi Reservoir,Multi-wave Reservoir, Upstream Reservoirs, Victory Reservoir in the first Division.
