摘　　要：基于新滩滑坡位移观测资料,运用数理统计均方差异常判据对滑坡失稳过程中的位移矢量角变化规律进行了初步的研究,发现随着边坡的失稳位移矢量角出现异常变化,表明位移矢量角具有较强的预测预报功能,说明在滑坡预测预报过程中,位移矢量角是一个不可忽视的变量。Based on the monitoring data of displacement which result from the Xintan landslide,this paper completes a study on the change of the displacement vector angle in the process of instability using MSE exception criteria.It is found that the displacement vector angle has a anomal along with the gradual failure of slope.It is indicated that the displacement vector angle has a strong prediction function.The result shows that the displacement vector angle is an important variable in the prediction of landslide.
