Geotechnical Soil Investigations
Geotechnical Investigations constitute a systematic and scientific process undertaken to evaluate the Engineering properties, Stratification, and in-situ behavior of subsurface Soils and Rock for the safe and economical design of civil engineering structures. These investigations provide essential data required to assess the Bearing Capacity, Settlement characteristics, Shear Strength, and Stability of the ground on which a structure or pavement is proposed.
The investigation program typically includes Subsurface exploration through boreholes, trial pits, or test pits to identify soil layers, groundwater conditions, and depth to hard strata. Field tests such as Standard Penetration Test (SPT), Dynamic Cone Penetration Test (DCPT), Plate Load Test, and Permeability tests are carried out to evaluate in-situ strength and deformation characteristics.
Collected soil samples are subjected to comprehensive Laboratory Testing, including grain size analysis, Atterberg limits, compaction characteristics, shear strength tests, consolidation tests, and California Bearing Ratio (CBR) tests. These tests determine critical parameters governing soil behavior under loading and environmental conditions.
