判明滑坡深度是局部和区域滑坡监测中的主要任务之一。为了解决这个问题,可以广泛使用地形的方法。这种方法使得有可能根据边坡断面的变化和表面位移的大小来确定滑坡的深度。在局部监测过程中,这个问题的解决,主要通过对地表基准点的控制。在区域监测工作中,根据对滑坡区重复进行的摄影经纬仪和空中摄影测量,就能取得必要的原始数值,同时也可通过单个滑坡的基准大地测量学的地形测量来达到这一目的。
Determining the depth of landslide is one of the main tasks in local and regional landslide monitoring. In order to solve this problem, the method of terrain can be widely used. This method makes it possible to determine the depth of the landslide according to the change of the slope section and the size of the surface displacement. In the local monitoring process, the solution to this problem is mainly through the control of the ground reference point. In the area of monitoring, based on the repeated photogrammetry and aerial photogrammetry of the landslide area, the necessary raw values can be obtained, as can the geodetic survey of a single landslide base geodesy.
