Geo-Technical Investigations
- Soil Boring: Detail the process of drilling boreholes to obtain soil samples for analysis. Discuss the different types of soil borings and their applications.
- Test Pits: Describe the excavation of test pits for direct observation and sampling of soil and near-surface conditions.
- Geophysical Surveys: Mention methods such as ground-penetrating radar (GPR) and electrical resistivity surveys for subsurface mapping.
- Standard Penetration Test (SPT): Explain how SPT is used to assess soil strength and density through penetration resistance.
- In-Situ Testing: Include tests like vane shear tests and pressuremeter tests to evaluate soil strength and behavior under in-situ conditions.
