Background
Landslide is a common address disaster with wide distribution, and casualties and economic losses of people are often caused. Therefore, landslide monitoring is always an important link for disaster prevention and reduction and providing basis for landslide control, wherein ground surface displacement measurement is the most important monitoring means. The displacement variation of the landslide is one of key physical quantities for describing the current state of the landslide, and the landslide stability can be analyzed by monitoring the dynamic displacement variation of the landslide, so that the safety warning range of the landslide is judged, the possibility of occurrence of the landslide can be evaluated, and early warning preparation can be made in time.
Among the various earth surface displacement monitoring methods, the GPS global positioning system is widely used. The GPS carries out space back intersection measurement through signals transmitted by satellites, determines the three-dimensional coordinates of monitoring points, and achieves the purpose of monitoring deformation by tracking the position change of the three-dimensional coordinates.

Specifically, the laser displacement meter 1 measures the displacement of the landslide by pulse measurement. Laser pulses are emitted at a landslide monitoring point through an emitting diode in the laser displacement sensor, and the light pulses irradiate the fixed target reflecting plate 2 at a far distance and return to a receiver of the laser displacement sensor after being reflected by the emitting plate. And recording the time interval from the laser emission time to the reflected light receiving time, and calculating the absolute distance between the laser displacement monitoring point and the target according to the transmission time of the light in the air to monitor the displacement of the landslide. Usually, under the field operation condition, the distance between the laser displacement meter 1 and the fixed target total reflection panel is not more than 10 meters, and the distance can be properly expanded to be within 30 meters under the specific condition. The angle between the laser displacement meter 1 and the normal of the fixed total reflection panel can be up to 70 degrees at most.
Specifically, according to the fact that the first displacement variation value is larger than the second displacement variation value and exceeds the preset value, various conditions can be judged: one situation is that the laser displacement meter 1 may have a miss or determine that the target is moving, in which case it needs to be verified whether the target is still fixed in place; the other is that the landslide point has an integral parallel landslide trend, and the equipment of the monitoring point moves in parallel along with the landslide, so that the change on the displacement is caused but the inclination angle does not change obviously, and in this case, the data monitoring frequency can be increased correspondingly.

Therefore, when the monitored inclination angle changes, the original displacement plus the inclination angle change displacement can be taken as the corrected actual displacement value delta D1'：ΔD1'＝D0+S1In which S is1A second displacement change value which is a movement in a direction away from the reflection plate 2. When the inclination angle change of the measuring body 3 inclines towards the direction close to the reflecting plate 2, the inclination angle change displacement can be subtracted from the original displacement to be used as the corrected actual displacement value delta D2'：ΔD2'＝D0-S2In which S is2In a direction close to the reflection plate 2Second displacement variation value of movement
