摘要:
为了研究某铀尾矿库在不同工况下渗流流态和安全系数,以南方某铀尾矿库为对象,耦合GEO-Studio软件中SLOPE/W和SEEP/W模块,并利用极限平衡理论模拟研究了不同工况下坝体渗流流态和安全系数。结果表明:水流主要通过尾粉土层流过尾矿坝,使水力坡降主要集中在初期坝坡前底部;随着水位上升,坝体中水力等势线越来越稀疏,同时尾矿坝3个渗流截面流速加大; 6~9度地震烈度激励下,尾矿坝安全系数维持在1.23~0.91之间,不能满足规程要求。建议初期坝坡坝底埋设排水管,减小水流对初期坝压力,同时对尾矿坝,特别是尾粉土层进行灌浆加固,提高尾矿坝稳定性。
Abstract:
In order to study the seepage flow pattern and the safety coefficient of a certain uranium tailings under different working conditions, taking a certain uranium tailings in southern China as the research object, the seepage flow pattern and the safety coefficient of dam body under different conditions were studied through simulation by using the limit equilibrium theory with coupling the SLOPE/W and SEEP/W modules in GEO-Studio software. The results showed that the water flow flowed through the tailings dam through the tailing silt layer mainly, which made the hydraulic gradient mainly concentrated on the front bottom of dam slope in the initial stage. With the rise of water level, the hydraulic equipotential lines in the dam body became increasingly sparse, and the flow velocity in three seepage sections of tailings dam increased. Under the effect of seismic intensity from level 6 to level 9, the safety coefficients of tailings dam maintained between 1.23 and 0.91, which could not meet the requirement of the regulation. It was suggested that the drain pipes should be buried at the bottom of dam slope in the initial stage, so as to reduce the pressure on the dam by the water flow in the initial stage. Meanwhile, the grouting reinforcement should be carried out on the tailings dam, especially the tailing silt layer, to improve the stability of the tailings dam.
