针对尾矿坝的安全现状,特别是由于水的原因引起坝体产生渗流而导致的失稳溃坝.为了得到尾矿坝的浸润线位置以及安全控制范围,运用大型软件Ansys分析了尾矿坝不同标高时的浸润线位置及变化情况,采用水上和水下不同的物理力学参数来分别计算.结果表明:该尾矿坝溢出点均在初期坝坝顶,此处容易发生管涌导致垮塌事故,须采取相应排渗措施,来降低坝体浸润线,从而保证坝体的稳定性;分析结果为尾矿坝以后的设计和安全检测提供了一定的理论依据,具有重要的借鉴意义.
In view of the safety status of the tailings dam, especially the instability dam that caused by the seepage of the dam due to the water.In order to get the location of the wetting line of the tailing dam and the scope of safety control, Ansys analyzed the tailings dam The locations and variations of the infiltration line at different elevation are calculated by using different physical and mechanical parameters of water and underwater.The results show that the overflow point of the tailings dam is at the top of the initial dam, Corresponding drainage measures should be taken to reduce the dam infiltration line so as to ensure the stability of the dam. The analysis results provide some theoretical basis for the design and safety testing of the tailings dam later, which is of great reference significance.
