岩质边坡渗流场中等效连续介质模型的应用

Equivalent Continuum Model and its Application to the Seepage Analysis of Rock Slope

在运用等效连续介质模型分析了裂隙岩体渗流场时,综合考虑并比较了单孔压水 试验和节理裂隙统计取得的渗透系数,获得了能较好反映原位地质环境的修正渗透张量.将 这种确定渗透张量的方法应用于某铁矿边坡工程渗流场分析中,取得了较好的结果.

During the analysis on the seepage field of fractured rock mass by using the equivalent continuum model, the coefficients of permeability obtained from the pump-in test and the field survey of rock mass structural faces are compared synthetically. Then the modified permeability tensor that can reflect the intrinsic geological environment elements is proposed. Finally, the method is applied to the seepage analysis of open-pit slope fractured rock mass successfully.
