As an absolutely necessary measure

monitoring on plays an important function during different phases of landslide treating; in virtue of monitoring

the real status

stability and distortion phase of landslide can be got

which will provide immediate basis for laying down primary precautions and schemes to harness landslides; it is real-time information feedback for slope control design optimization

construction informatization and project quality guaranteed during landslide being treated; after treating

the monitoring data is regarded as the direct indicator of treating effect. Combined with engineering monitoring practice during a road cut slope treating

the monitoring systems about different treating phases and the function of the obtained information are introduced.
