At present, the traditional surface deformation monitoring methods mainly include: GNSS, total station, optical fiber sensor, etc.
Pros:It is easy to operate and low cost.
Cons:
Contact monitoring: Difficult to install in hazardous areas and long construction time.
Point monitoring: Measurement spatial discontinuity.
It is difficult to be affected by foggy and rainy weather.
The effect of comprehensive monitoring needs to be improved, especially when it comes to sudden disasters.
New means of deformation monitoring-Shenbei scientific instrument slope deformation monitoring radar **Geological disaster emergency rescue equipment
Shenbei slope deformation monitoring radar is mainly used for emergency monitoring and automatic early warning of slope stability.
Shenbei scientific instrument slope radar can monitor the small deformation of the surface of the object, which is mainly suitable for:
1) Landslide, collapse and settlement monitoring of various geological hidden danger points such as high and steep slopes and dangerous rock masses (2) Emergency monitoring of geology, emergency, railway, electric power, urban and other industries.
Principle: Radar – emits electromagnetic waves (non-contact, all-weather all day).
Imaging radar – to obtain an image of the target (area irradiation).
Interferometric processing – measurement of deformation (ku-band, millimeter wave, high accuracy).
To sum up, although the traditional deformation monitoring methods have their application scenarios and advantages, the slope deformation monitoring radar has shown its superiority in many aspects. In practical application, the appropriate monitoring means can be selected according to the needs, or it can be combined with traditional means and radar monitoring to achieve more comprehensive and accurate deformation monitoring.
