| 摘 要： | 根据钻孔资料结合宏观地质调查资料分别作分段线形插值函数、拉格朗日插值函数和样条插值函数 ,用得出的插值函数来表征滑动面。并将插值函数与传统的圆弧滑动面假设分析对比。以南京狮子山东南坡滑坡为例 ,根据不同的插值滑动面 ,采用普遍条分法计算滑坡稳定性系数。最后 ,对不同的结果作了分析对比 ,认为过特征位置采用样条插值函数所表示的滑动面较好地符合实际情况

| Abstract: | In this paper, according to the existing boring data combined with macro geological investigation material, the landslide plane is represented by an interpolation function,which is in the wake analysed and compared with the traditional hyposesis of arched landslide plane. The method is illustrated through a case of landslide,Shizi Mt.landslide,Nanjing. On the basis of the interpolation function, the stability coefficient of landslide is calculated with the N.Janbu method. At last, the writer suggests that the spline interpolation function be applied to represent the landslide plane,by comparison of different landslide plane. |
