Frequently Asked Questions
What is effective stress and why is it important?
Effective stress is the stress transmitted through soil particles (total stress minus pore pressure), determining soil strength and deformation behavior, fundamental to all geotechnical design.
How does consolidation settlement differ from immediate settlement?
Immediate settlement occurs from elastic deformation, while consolidation settlement develops over time as pore water drains and soil particles rearrange under sustained loading.
What is Boussinesq theory used for?
Boussinesq theory calculates stress distribution in soils due to surface point loads, essential for foundation design and determining required bearing capacity for different soil depths.
What is the Mohr-Coulomb failure criterion?
It states that soil fails when shear stress reaches τ = c + σ tan φ, where c is cohesion and φ is friction angle, forming the basis for shear strength analysis in all soil mechanics problems.
How should I prepare for CE3404 exams?
Focus on phase relationship formulas, effective stress calculations, Boussinesq stress distribution, consolidation settlement numericals, bearing capacity determination, shear strength testing, and slope stability analysis.
