尾矿坝渗透静力稳定分析

边坡稳定的条分法中，条间剪切力的作用效应根据分析方法的不同，对稳定系数的计算结果存在较大的差异。有效应力分析方法中依据渗流场的计算分析得到条间孔隙水压力。基于Bishop条间力的假定原理，提出一种新的条间孔隙水压力的分析方法，以确定边坡的最小稳定系数。实际工程计算反映出不同计算方法的差异及新方法的实用性。

Static stability analysis of seepage of tailings dam

There is greater difference for calculating result for slope stability factor because of difference of hypothesis for shear action of inter-slice in slice method of the slope stability. Based on computation and analysis of seepage field, pore water pressure of inter-slice is defined in the effective stress method. In the light of hypothesis of Bishop’s force of inter-slice, a new analysis method for pore water pressure of inter-slice is suggested for minimum stability factor of slope. Finally, an example of real engineering shows, the difference of calculated results with different methods and that the new means is practical.
