| Zusammenfassung |
Sediments produced by a slope failure of the toe of a landslide are assumed
to prevent the spread of the failure. Thus, sediment removal is an emergency
measure that must be done safely while the slope is observed. Observation
must also be done safely without requiring workers to enter the failed slope
to avoid secondary disasters.
Generally, a non-prism type totalstation is useful to measure ground
displacement under such circumstances, because this type of totalstation can
be used without placing targets on the slope. However, the lack of prisms
results in problems related to the objectivity of measurement data,
collimation error of the totalstation, measurement at night, and so on.
The authors have developed targets and a remote target placing method in
order to resolve the above problems. As a result, we have established remote
measurement technique for ground displacement on failed slopes at the toes
of landslides. This paper describes the measurement technique that has been
developed. |
