Geotechnical Engineering

Geotechnical Engineering for GATE Civil and ESE covers: soil classification (IS soil classification, Atterberg limits), permeability and seepage, effective stress and pore water pressure, consolidation (Terzaghi's theory), shear strength (Mohr-Coulomb criterion, triaxial and direct shear tests), bearing capacity of shallow foundations (Terzaghi and Meyerhof equations), slope stability, lateral earth pressure (Rankine and Coulomb theories), and pile foundations.

These tests are ideal for undergraduate civil engineering students and candidates preparing for GATE Civil Engineering, ESE Prelims, SSC JE Civil, state PSC/PWD exams, and any other civil engineering competitive examination. All tests are completely free — no account needed.

Geotechnical Engineering carries approximately 10–14% weightage in GATE Civil Engineering, typically 10–14 marks out of 100. It is consistently one of the highest-scoring subjects in GATE Civil. Consolidation, shear strength, bearing capacity, and effective stress are the most frequently tested topics.

In ESE Prelims Paper II (Civil Engineering), Geotechnical Engineering (Soil Mechanics and Foundation Engineering) typically accounts for 20–25 questions, carrying 40–50 marks out of 300. Both theoretical concepts and numerical problems from soil classification, consolidation, shear strength, and foundation design are tested.

For SSC JE Civil Engineering, important Soil Mechanics topics include: types of soil and their properties (grain size, consistency limits), permeability (Darcy's law), compaction (Standard and Modified Proctor test), bearing capacity of soils, types of foundations (shallow vs. deep), and basics of retaining walls. SSC JE tests conceptual and formula-based questions rather than complex numerical derivations.
