CMP 305 Final Exam Questions and
Revised Answers

Soil Exploring Types - Answer-- Direct
- Sem-direct
- Geophysical

Direct Soil Exploration types - Answer-- Test Pit
- Split Barrel
- Standard Penetration
- Shelby Tube

Test pit - Answer-- ADV: undisturbed sample, can see soil profile
- DIS: limited to shallow excavation, safety

Split Barrel and Standard Penetration - Answer-- Measures resistance to penetration
- 2" Diameter hollow rod
- l= 30"
- Driven in by drop hammer

Shelby Tube - Answer-- Thin wall Tube 2-5" Dia.
- Length = 4 feet
- Pushed in not driven in
- Used with hollow core auger
- Sampling interval = 5'

Semi-Direct Soil Exploration Types - Answer-- Auger Drilling
- Rotary Drill
- Wash-boring
- Drilling Rock
- Cone Penetrometer

Auger Drilling (2 types) - Answer-- Solid: Dry Regions, auger is removed for sample
- Hollow: Sample through auger, faster, *use in Michigan*

-Dis: Disturbed sample

Rotary Drill (Auger with clay slurry) - Answer-- Slurry moves soil up, stabilizes sides by
coating the sides of the hole.

, Wash-boring - Answer-- Drill with jet water
- Floats material out
- Casing required
- ADV: Small unit
- DIS: Disturbed sample, water content

Cone Penetrometer - Answer-- Pushed into ground, records reading
- ADV: provides a continuous record of test results.
- DIS: no lab sample

Drilling Rock - Answer-- Hard rock use diamond carbide tip
- RQD (Rock Quality Design): Rock Sample tested to determine strength

Geophysical Soil Tests - Answer-- Usually with road work
- Fast quick results, may not be as accurate but good for generalities
- Borings still required to determine soil properties
- Test types: seismic and electrical

Seismic Geophysical Soil Test - Answer-- Velocities transmitted through soil
- Greater the density the faster the waves travel
- Sensor picks up waves from explosions
- Dis: Boundaries poorly defined

Electrical Geophysical Soil Test - Answer-- Measures electrical resistance through soil
- Effected by water and ion concentration: More water less resistance. (Clay soils have
the most ions)

Ground Water Table - Answer-- Very Important to know where it is!!
- Effects soil bearing capacity
- Changes with seasons
- Determining water table depth = existing well

Planning for Dewatering System - Answer-- Need to know elevation of ground water
and Permeability of soil

Compaction - Answer-- Improves soil engineering properties
- Process of increasing soil density by removing air from void space

Consolidation - Answer-- Increases the density of saturated (cohesive) soil by expulsion
of water from void spaces.
- Takes months years

Consolidation vs Compaction - Answer-Compaction is quicker than Consolidation,
Consolidation happens over time

Four basic compaction forces - Answer-- Static weight
