摘要
介绍了都龙锡矿排土场主要是由采场爆破的岩石堆排而成,通过现场原位直剪试验,获得了排土场松散岩土体直接剪切时的剪应力-水平位移关系曲线,为矿山排土场边坡稳定性评价提供了较为真实的抗剪强度参数。
Dulong Tin Ore Dumping Site mainly consists of loose rock and soil from stope. The relation curve of shear stress-horizontal displacement at direct shear of loose rock and soil in the dumping site is achieved through the field direct shear test. It provides real shear strength parameters for slope stability evaluation of mine dumping site.
