the reference station and the measuring station are both used for determining three-dimensional coordinates of the reference station and the measuring station by receiving satellite signals through a GNSS host based on the GNSS technology.
In time series, the deformation of the landslide monitoring area is measured by comparing the variables of the three-dimensional coordinate differences of the measuring station and the reference station.
In actual use, the reference station is used as the origin of the three-dimensional coordinate system, and the three-dimensional coordinate change values of the measuring stations are compared.
Landslide or collapse is generally classified into a development period and an occurrence period according to the characteristics of geological disasters of the side slope, and corresponding monitoring methods are also classified into two types.
For slope monitoring in the development period, the absolute displacement of the measuring station is monitored to dynamically monitor the deformation of the slope in real time, namely, the initial installation coordinate is taken as an origin, the three-dimensional coordinate of the measuring station, which changes along with time, is calculated in real time, and the long-term geological movement development condition of the monitoring point is reflected in the long-term monitoring process.
