摘要
以东北某露天矿排土场作为研究背景,采用Geo-slope极限平衡理论与FLAC数值模拟相结合的方法,深入分析排土场在多种影响因素作用下的稳定性。重点对排土场表土层厚度、排弃物堆置高度和角度以及地下水等主要影响因素进行系统的分析与研究,得到排土场的逐渐移动变形、直至破坏的整个过程。同时揭示了在有水影响的情况下,排土场岩体变形移动规律,提出了防治措施,保证排土场安全可靠的排放。
The study background of this paper is the dump of a surface mine in China Northeast, it makes a depth analysis of stability with different influence factors, by using method of combining the Geo-slope limit equilibrium method with FLAC numeric simulation. Thickness of surface soft, the height of exhaust, angle, ground water and so on of dump is studied. At the same time the paper reveals with influence of the water the dump of rock the deformation and displacement law and provide prevention measures to ensure safe and reliable of dump.
