Abstract
Tailings dam heightening change the seepage field characteristics of landfill material and influence the safety of the dam. Based on the actual drilling exploration results and permeability coefficient obtained from penetration test of indoor drill hole sampling,the best inver-sion actual seepage model was established,by means of the application of two-dimensional finite element numerical calculation software GEO-SEEP,to get the calculation analysis of heightening seepage field of tailings dam,and the key elements distribution map of seepage field were obtained. The analysis results show that the heightening tailings dam reservoir infiltration line on the high side in natural conditions make against to the safe and stable operation of the tailings dam. Therefore,put forward a preliminary scheme of strengthen drainage facilities in optimization scheme,through the numerical simulation validation,the scheme can reduce the dam saturation line. In the drainage facilities layout of tailings dam,through the seepage simulation,the rationality of drainage scheme can be examined,provided reliable basis and tech-nical support for the safety design and construction of the tailings dam drainage facilities.关键词
