Advanced Geotechnical Engineering focuses on the complex analysis, design, and behavior of soil and rock in response to various engineering applications. It goes beyond basic soil mechanics to address real-world challenges involving infrastructure, foundations, tunnels, slopes, embankments, and earth-retaining structures.
Key Areas of Study:
- Soil-Structure Interaction (SSI):
- Interaction between soil and foundation systems.
- Modeling how structures affect soil behavior under loads.
- Dynamic SSI under seismic conditions.
- Advanced Soil Mechanics:
- Nonlinear and unsaturated soil behavior.
- Consolidation, creep, and swelling characteristics.
- Stress-strain analysis and failure criteria.
- Foundation Engineering:
- Design of deep and shallow foundations.
- Pile foundations, caissons, and raft foundations.
- Settlement analysis and mitigation techniques.
- Slope Stability and Landslides:
- Analysis of slope failure mechanisms.
- Use of limit equilibrium and finite element methods.
- Slope stabilization techniques (anchors, geosynthetics, drainage).
- Tunneling and Underground Construction:
- Tunnel boring machines (TBM), cut-and-cover, and NATM methods.
- Ground support systems and shotcrete design.
- Monitoring ground movement and mitigating settlement.
- Seismic Geotechnical Engineering:
- Site response analysis and liquefaction studies.
- Seismic design of retaining walls and foundations.
- Earthquake-resistant infrastructure and retrofitting.
- Geotechnical Earthquake Engineering:
- Ground motion amplification and soil liquefaction.
