露天矿边坡岩体裂隙含水介质渗流场边界元分析

THE ANALYSIS OF THE PERMEABILITY FIELD IN THE JOINTED MEDIA OF THE OPEN PIT SLOPE WITH BOUNDARY ELEMENT METHOD

本文研究了裂隙岩体各向异性的渗透系数,以及各向异性介质中潜水非稳定流的边界单元法.预测了露天矿开采的不同阶段,边坡体中潜水位的变化,为边坡稳定性分析提供了重要参数.

The properties of anisotopic permeability in jointed rock masses and the boundary element method(BEM)for the calculation of unsteady flow in unconfined anisotopic media are studied in this paper The changes of the position of water table are al- so predicted at various mining stages of the open pit.This lays a foundation of analysing the stability of the slope.
