大型露天铁矿边坡三维渗流分析研究

Study on 3D seepage analysis of a large open-pit slope

渗流是影响边坡稳定性的重要因素,也是边坡稳定性研究的基础。本文以水厂铁矿露天北采场西帮边坡为研究对象,采用FLAC3D有限差分软件,对Ⅱ地质分区内剖面1至剖面7之间的坡体进行了三维渗流场模拟分析,得出坡体整体及4个剖面的渗流场分布变化规律,为进一步进行边坡稳定性分析提供了基础。

Seepage is not only an important factor affecting the stability of high rock slope but also is one of the fundamental contents of slope stability investigation. Based on west slope of north stope in the Shuichang open pit mine, 3D simulation of seepage field using FLACaD was applied to the slope between section No. 1 and section No. 7 in the geological partition II. The distribution law of seepage field in both slope and four of its sections was obtained. A sound basis was provided for further analysis of slope stability.
