摘要:
本文结合工程实例,以吊水壶尾矿坝为背景,建立现状尾矿坝三维模型,利用三维有限元法反演分析现状尾矿坝的渗流场,将计算结果与勘察的浸润面对比分析,验证模型的可靠性和合理性。基于此模型建立加高后的尾矿坝三维模型,计算正常蓄水位和设计洪水位两种工况下的渗流场,分析坝体浸润面埋深、滩长、渗流坡降等,结果表明,不设排渗措施时,尾矿坝干滩长度、浸润面埋深均能满足规范要求,而且尖流性态良好,满足渗透稳定。提出该尾矿坎可通过加高工程来进行渗流控制的建议。
Abstract:
Combining with practical engineering,the present Diaoshuihu tailing dam was simulated in this paper,the seepage field was calculated by threedimensional finite method, the calculated phreatic line was compared with the measured result to confirm the rationality of the model. Then,the heightened tailing dam based on the present dam was given in this paper,the depth of phreatic surface、beach length and seepage gradient were analysed on the condition of normal water level and design flood water level,the control proposals of seepage flow were put forward.
