姑山铁矿复杂边坡含水层渗流数值计算

Numerical Calculation of the Filtrate of Complex Water-containing Layers of Slope at Gushan Iron Mine

姑山铁矿为大水矿床 ,进行边坡稳定性分析首先要进行边坡渗流场计算。根据姑山采场的具体水文地质条件 ,应用 2维和 3维有限元结合不变网格节点虚流量法 ,并对边坡复杂含水层进行适当的简化 ,进行边坡渗流场数值计算 ,结果满足工程研究需要 。

Gushan Iron Mine is a wellknown heavy water ore deposit. The calculation of slope infiltration field was required to do first in slope stability analysis. In light of the real hydrological geological conditions of Gushan pit, a method combining 2D and 3D finite element method with non variant node virtural flow method was used, with appropriate simplification of complex water containing layers of slope, to do the numerical calculation of the slope infiltration field. The calculation results met the requirement of the engineering research and coincided well with the on site data.
