What is total head equal to?
Elevation Head + Pressure Head
Define Elevation Head and Pressure Head
Elevation Head: Difference between a given point and the free water level
Pressure Head: Difference between the datum and given point
Relationship between Undrained Shear Strength, Cohesion, and Unconfined Compression Strength
Su = C
Su = C = 0.5 * qu
What is the FS against Overturning? Sliding?
Overturning: Moment of Resisting / Moment of Overturning
Sliding: Force of Resisting / Force of Overturning
What is the use of Seismic Refraction?
Determining depth, thickness, and shear wave velocity of subgrade layers
Which reference has information about rock source?

What soil types does immediate (also known as elastic) settlement occur in?
All Types
When does immediate/elastic settlement occur?
During and right after construction
Total head loss is generally considered to be what throughout the soil length?
linear
What do you need to do if you’re considering local or punching shear failure in a problem?
Reduce the soil strength parameters
What is jet grouting?
Use of air, water, and grout to erode soil and replace with grout. Used for creating cutoff walls and continuous underpinning.
If you’re not given a coefficient of friction, what is a good value to use?
tangent of the internal friction angle of native
What is the friction force for a sliding check?
Weight * tan (internal friction angle of native)
What is the equation for deformation?
deformation = PL / AE
