What is the main purpose of a soil boring test?

What role does an auger play in geotechnical engineering?

In geology, what does the term 'hypocenter' refer to?

What technique involves using a rotating drill bit to penetrate the ground for geotechnical purposes?

Which type of fault is characterized by rocks moving past each other horizontally with little vertical movement?

What is the primary objective of wash boring in geotechnical investigations?

Auger boring collects soil samples for analysis, aiding in geotechnical investigations.
Wash boring involves injecting water or a mud-like substance while drilling, primarily to stabilize the borehole and facilitate soil recovery.
The chopping bit on a drilling rod breaks down soil layers, allowing for better sampling during a soil boring test.

The hypocenter marks the precise location within the Earth where an earthquake originates.
Shifting rocks during an earthquake generate seismic waves, specifically P-waves and S-waves.
Seismic wave amplitude measures the energy released during an earthquake, indicating its strength.

Rotary drilling efficiently penetrates soils and rocks, suitable for various geological conditions.
Percussion drilling features a heavy cutting or hammering bit, relying on gravity to drive the bit downwards attached to a rope or cable.
A tripod supports the drilling apparatus in percussion drilling, stabilizing it during operation.
Certain drilling methods may yield poor-quality undisturbed soil samples, affecting analysis accuracy.

The primary objective of a soil boring test is to assess subsurface conditions for construction or engineering projects.
Geotechnical engineering utilizes augers to effectively retrieve samples for evaluating soil properties and stability.
Wash boring serves to determine soil layering and condition through continuous sample retrieval in soft or saturated grounds.

A strike-slip fault is characterized by the horizontal movement of rocks with minimal vertical displacement, affecting earthquake and tectonic studies.
