邓上银矿采选矿厂边坡稳定性评价

拟建的承德邓上银矿采选矿厂依山傍坡，边坡稳定性是该场地的主要工程地质问题之一。本文采用“简布极限平衡普通条分法”对稳定性较差的边坡典型剖面进行稳定性评价，不仅可对边坡进行整体稳定性验算，还可对划分的每一条块进行稳定性计算。计算结果表明，该边坡的整体稳定性较好，不会产生整体滑坡。

Evaluation on Slope Stability of the Mining-Dressing Plant at Dengshang Silver Mine

The mining and dressing plant to be built is to be located along a mountainous slope where slope stability would present one of the major engineering geological concerns. In the paper, the Janbu's limiting equilibrium common slicing method is used to evaluate stability of typical section planes at relatively unstable localities. The Janbu's method not only provides check computation for overall stability of the entire slope, but also makes it possible to determine the stability of each slice divided. Results indicate that the slope at the chosen site is very stable as a whole and will not cause slope failure.
