Study on dynamic real-time deformation monitoring of landslide based on beidou navigation system

摘要

The beidou navigation system is used to monitor the landslide in a timely manner. At the same time, through in-depth analysis of the characteristics of the landslide deformation, the movement law of the landslide is mastered, the current state of the deformation body is understood, and the effect of disaster prevention and reduction is achieved. This paper mainly studies the application of high precision positioning of beidou satellite navigation system, including the development of the whole monitoring system. The principle and characteristics of the three methods based on satellite system are expounded from the mathematical model, and the performance indexes of the three methods are verified by the measured data. The combined application analysis of GNSS, displacement meter and measurement robot was further carried out. Finally, a landslide monitoring system integrating software and hardware, including GNSS receiver, was developed. The experimental results show that the dynamic real-time deformation monitoring of landslide can effectively monitor the shape and variant in space and time, and detect the change of its position in time, so as to make correct preventive measures for the possible situation in advance.
