不同时间窗下滑坡加速开始点动态识别研究
Research on dynamic identification of the starting point of landslide acceleration in different time windows
摘要
Abstract
To study the dynamic identification rules of the starting point of landslide acceleration under different time windows,based on the characteristics of the uniform deformation stage in the three-stage creep deformation theory,the hypothesis testing method was applied to dynamically identify the critical moment point between the uniform stage and the acceleration stage.The influence of different time windows on the identification of the starting point of acceleration deformation was investigated.Combined with the case of landslide early warning,the effect of the identified acceleration moment point on the prediction of landslide time using the reciprocal of speed model was discussed.The results show that the hypothesis testing method can effectively determine the critical moment point between the uniform and acceleration stages of creep deformation.Different time windows have certain adaptability to the identification of the starting point of acceleration,and a larger time window cannot obtain an effective starting point of acceleration.When applying the landslide prediction model to predict the landslide time,the data after the acceleration moment point determined by using a smaller time window is more accurate for prediction.关键词
