摘　　要：根据膨胀土滑动面的显著特征,提出一种简易确定滑动面的方法。该方法的主要思想是通过麻花钻孔取样寻找含水量突出带和灰白土富集带来鉴别滑动面的深度。通过典型膨胀土滑坡的实践与分析,证明该判断方法是有效的。A simple method to determine of slip plane of expansive soil slope is put forward herein based on the special characteristics of the slip plane of the expansive soils. The main concept of the method is to distinguish the depth of the slip plane with the extruding water content zone and the enriched gray clay zone determined from the samples taken by manual twist drill. It is demonstrated that this determination method is effective through the typical engineering practice and the analysis concerned.
