| 摘 要： | The long-term quantitative monitoring for slope displacements is one of the important means of the middle-term or short-term forecast for landslide and the analysis on the sliding properties.Because of the differences of slope's boundary condition and the changes of many affecting factors such as the physical dynamic properties of slope-body,the stress field in it,ect,the monitoring displacement values of a slope are generally composed of creep deformation, compressive deformation and whole sliding deformation.The first and second displacements,which belong to local deformation,reflect the acting by the local stress,and the third displacement,which results from the acting of slope's overall stress field, represents the overall-trend displacement.Therefore, it is very significant that the whole-trend displacement is analyzed and judged correctly and systematically to the slope's stability evaluation and the forecast for landslide. This paper, using the long-term monitoring data of displacement of Xintan s
