摘　　要：针对德兴铜矿4号特大型尾矿库中采用中线法堆坝技术工艺所形成的尾矿堆积坝,通过现场地质调查和室内试验充分调查了尾矿库工程地质特性,定性分析了该尾矿库稳定性。通过上述稳定性计算模型的建立,运用Slide软件自动搜索尾矿库坝内潜在的滑动面并计算分析尾矿库坝可能存在的最危险滑坡的稳定性系数,使用Geostuido中的Seep模块进行计算,计算出各工况下坝体内的压力水头、流场分布情况和地下水流动矢量,对形成坝体高边坡的稳定性进行了分析和预测,并作出了相应分析及评价。Based on the tailing stacking dams caused by the center-line damming technique adopted at No.4 Extra-large tailings pond at Dexing Copper Mine,the paper investigates the geological features of the tailings pond project by on-site geological surveys and indoor experiments,undertakes the qualitative analysis of its stability,applies Slide software to have the automatic exploration for the potential sliding surfaces and calculate the stability coefficients of the possible hazardous sliding slopes based on the establishment of the stability calculation models,finishes the calculation by using the Seep model of Geostudio to figure out the pressure head,the distribution of flow field,and the flowing vector of underground water at the dam in different construction conditions,attains the analysis and prediction of the stability of the dam’s tall slopes,and points out the respective analysis and evaluation.
