| Summary: | Electrical resistivity survey and the geotechnical SPT blow counts (N value) method were simultaneously analyze to investigate the stability of the earth sub-surface. The coupling of these heterogeneous field methods provided a chance to understand the status of underground materials by comparing the geophysical and geotechnical view. The analysis shows that the zones with low resistivity value generally have low N value, which means low stiffness. However, some zones with a high resistivity pattern are not accompanied by an increase of its N value, and are even showing a lower N value. |
