摘要
文章结合E区工程地质条件和开采方案对E区边坡建立三维地质模型,采用FLAC3D有限差分软件对从原始地表开挖至坑底1230 m平台全过程进行数值模拟,并从应力场、位移场、塑性区分布3个方面进行分析,从而对持续开挖至坑底过程中整个E区边坡稳定性及稳定性发展情况进行预测。
In the paper, based on the engineering geological conditions and mining scheme of E zone, the three -di- mensional geological model is established for slope of E zone. Using FLAC3D finite difference software, numerical simula- tion is done for the whole process of excavation from the original surface to the 1 230 m platform of pit bottom. It is analyzed from three aspects of stress field, displacement field and plastic zone, so as to predict the stability and stability development situation for slope of E zone during the process of continuous excavation to the pit bottom, which provides a more reasonable basis of the precaution and the design of treatment scheme for the lower excavation slope.
