摘要
以马钢某矿为工程背景,针对内排土场的稳定性情况,在考察排土场所处工程地质环境的基础上,利用FLAC数值模拟分析法对内排土场进行稳定性分析。在排土场堆积过程中,排土处最大主应力差随着排土高度的增加,岩土体破坏区域不断加大;达到终排设计高度后,排土场内部由于排土场和基岩的剪切和土体内部自重固结产生了塑性破坏和剪切滑动面。
Taken some mine as an engineering example,and based on the basis of examining the engineering geology environment,numerical analysis the stability of the waste-dump by FLAC.Accumulation in the process dump,the maximum principal stress difference at dumping height with the increase of increasing regional rock and soil damage;reach the final row of the design altitude,soil and within the rock dump and soil within the shear generated gravity consolidation of plastic damage,destruction had the shear slip surface.
