Drilling and sampling of soil and rock for analysis and deciding on foundation type, depth, and strength is a standard procedure for any large infrastructure project, may it be road and bridge construction, harbor jetty construction, or very high-rise building design.
The design of building foundations, roadways, excavation, fills, and slopes requires an understanding of soil strength; soil characteristics, and consideration of problem soils and how soil behaves under imposed loads. Drilling and core samples provide the necessary samples for laboratory soil and rock tests and for on-site field testing. It is important to follow the criteria and guidelines so the appropriate drilling methods are selected especially since subsurface exploration is expensive but not nearly as expensive as for a project failure.
The course is designed and conducted as per contents of US Dept of Transportation FHWA Publication No. FHWA NHI-01-031 “Subsurface Investigation-Geotechnical Site Characterization” – Chapters 2 & 3.
What will I learn?
- 1. Grasp subsurface exploration guidelines for soil and rock drilling and sampling.
- 2. Know minimum boring depth and frequency requirements for various construction types.
- 3. Understand how subgrade conditions dictate equipment selection: soil boring or rock drilling.
- 4. Recognize the appropriate drilling and sampling methods based on construction type.
- 5. Understand drilling method pros and cons, choosing equipment based on encountered soil and groundwater conditions.
- 6. Be familiar with drilling fluid use for different soil and groundwater conditions
- 7. Understand boring and sampling equipment operation and parameters.
- 8. Recognize undisturbed sample acquisition and when specialized procedures are needed.
- 9. Acknowledge the importance of visual observations and data recording during drilling, particularly for boring logs.
