Geotech Investigation
Geotechnical investigation is a crucial step in the planning and design of any construction project involving structures that interact with the ground. This investigation assesses the physical properties of the soil and rock at a construction site. Here’s an overview of the geotechnical investigation process:
1. Desk Study:
- Review of existing geological, topographical, and hydrological information.
- Examination of historical data, maps, and reports.
2. Site Visit:
- Physical inspection of the site.
- Identification of potential geotechnical issues.
3. Subsurface Exploration:
Boreholes:
- Drilling holes into the ground to collect soil and rock samples at various depths.
- Samples are recovered for laboratory testing.
Soil Testing:
- Determines grain size distribution, moisture content, compaction characteristics, and shear strength.
- Triaxial tests, consolidation tests, and direct shear tests may be conducted.
