摘要
国内外对排土场极限堆载高度的理论计算缺乏研究,目前尚无成熟的统一理论计算方法。文章结合永平铜矿西部排土场的工程实例,在进行边坡工程地质条件勘察与排土场岩土物理力学性质试验研究的基础上,采用数值计算方法对排土场进行了分层堆载数值模拟计算。通过对计算结果的分析,得到位移、塑性区与安全系数随堆载高度的变化规律,并确定了该排土场的极限堆载高度。
There are not much research on determination of the critical height of the open-pit dumps at home and abroad and there are not mature theories yet. In this paper, based on the investigation data available on the engineering geology conditions of the west dump of Yongping Copper Mine and research on physical mechanic property of rock and soil in dumping site, the effect of layered loading of the dump is analyzed by the numerical simulation. Based on computed result, the characterization of displacement, plastic zone and safety factor changing with the loading height is obtained. The critical height of the west dump is determinated.
