IS 2720 — Methods of test for soils, Part 39: Direct shear test for soils containing gravel, Section 2: In-situ shear test
IS 2720 Part 39 Section 2 (1979) specifies the procedure for conducting in-situ direct shear tests on soils containing gravel and cobblestones to determine their shear strength parameters. It provides detailed methods for sample preparation, loading, measurement, and result interpretation, ensuring reliable assessment of soil shear resistance under field conditions. This standard is essential for geotechnical engineers and researchers involved in foundation design and soil stability analysis where coarse-grained soils are encountered.
