PHYSICAL MODELING FOR DETERMINATION SLIP PLANE OF LANDSLIDE USING GEOELECTRICAL METHODE

Sari

A physical modeling has been conducted in a
laboratory scale, to determine the slip plane of
landslides. The physical model was installed
in a container which is filled by landslide
material (moist silty soil) and massive
material as the host rock. The layer models
are consist of six types of landslide situation
then measured by geoelctrical method in
centimetre scale. The result of geoelctrical
measurement showed subsurface image by
their own resistivity value. The host rock
material has a high resistivity (range from:
100 to 150 Ωm) value, compared to resistivity
values of landslide material(range from: 25 to
85Ωm). Border of difference layer creates a
layer as known as slip plane of landslide.
Thegeoelctrical image of subsurface also
measured the depth of slip plane.
