摘要:
针对干堆尾矿库设计时缺乏子坝结构参数取值依据的实际困难，采用数值试验和工程实证相结合的方法，系统研究了干堆尾矿库坝体结构参数对稳定性的响应规律，提出干堆尾矿库子坝结构参数选取方法。结果表明：堆坝安全系数Fs随子坝高h降低整体呈先增后减的变化规律，峰值为最佳子坝高，其值与堆积坝总高呈正相关，通常取值为堆积坝总高的1/5-1/7；安全系数Fs与马道宽d呈正相关，推荐在3-6m范围取值。
Abstract:
It is a practical difficulty that there is not a standard for selecting the structure parameters of subdams when designing a dry tailing dam. In view of this issue, the response laws of stability by the structure parameters of dry tailings dams were studied by numerical experiment and example verification. The results showed that the safety factors（FS）of the dry tailing dam will increase firstly then decrease as the height of subdams decrease by degrees. The peak point is the best value point. What’s more, the optimum height of subdam has a positive correlation with the total height of dry tailing dam, of which the best value is usually designed at 1/5 to 1/7 Furthermore, there is a positive correlation between FS and the width of subdams. The recommended value of subdam width ranges 3 metres to 6 metres.
