The Weak Soil Investigation at the Slope Zone in the Hot Spring Area, Rokan Hulu, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2019
The slope failure can occur due to the soil on the slope area is relatively porous and the surface water is easily to move in the soil. The zone of the weak zone of the soil should be detected early to avoid the ground mass movement on the slope area ...

Soil Parameters Model Prediction via Resistivity Value Limit to Shallow Subsurface Areas

Shock and Vibration, 2022
Geotechnical engineering design necessitates a study of soil parameters for calculation purposes. As a complement to the conventional method, a resistivity survey can give preliminary results in a short amount of time.

Grounding System Adequacy of HV/MV Substations in Areas With Reduced Accessibility [PDF]

, 2015
The adequacy of grounding systems has to be verified periodically in the operational time. With urban development and buildings growth adjacent to power systems as HV/MV substations, it is very rare to have area around with sufficient accessibility for ...
