摘要
分析了土坡滑动稳定性计算的条分法及其存在问题 ,并提出了圆弧滑动的有限元法 ,以三角形单元的渗透力取代垂直条块周边的水压力 ,正确考虑了渗流方向及其力矩的影响 ,不仅提高了计算精度 ,而且连续计算渗流与滑坡 ,使计算过程简便迅速。
In this paper the slices method for sliding stabil ity calculation of e arth slope is analyzed and its existing problems are indicated. At the same time the f inite element method for circular slip surface is proposed,for which the pore w ater pressure acting around each vertical slice is replaced by seepage force of triangular element. So the seepage direction with its effect of moment has been considered correctly .Not only the accuracy but also the convenience in calculation is increased due to that the stability calculation i s sequentially carried out after seepage calculation in one computer program.
