In situ tests give a more realistic picture of soil properties basically because of two reasons: i. The in situ tests cover a larger area and volume of soil mass than the laboratory tests which are conducted on small-size samples of soil. ii. Several site factors, such as non-homogeneity of soil, groundwater table, moisture content, cracks, fissures existing in the [...]
