This comprehensive course offers a complete introduction to geotechnical engineering and retaining wall design. Students will learn about the essential properties of soil and rock and how they interact with structures. The course emphasizes the role of geotechnical engineering in ensuring structural safety and sustainability, along with the importance of retaining walls for erosion control, structural stability, and creating level surfaces on sloping terrain.

Key principles and terminology related to retaining walls are introduced, including the forces acting on them and the various types: gravity, semi-gravity, cantilever, counterfort, anchored, and mechanically stabilized earth retaining walls.

Students will explore the categories of lateral earth pressure, including at-rest, active, and passive conditions, as well as the design process involved. The course also addresses construction materials, the need for thorough site investigation to ensure durability and serviceability, and the calculation of lateral earth pressure coefficients using Rankine and Coulomb earth pressure theories.

The curriculum also highlights the need to design structures to withstand natural hazards such as earthquakes and floods. It discusses building codes that specify expected structural lifespans and the importance of designing for long-term performance.

Case studies and examples of retaining wall failures are included to underscore the consequences of poor design and the value of proper investigation. The course also compares strategies for rehabilitation versus full replacement of structures.

Upon completion, students will be equipped with the knowledge and skills to design and analyze safe, durable, and reliable retaining walls. They will also develop a strong foundation in geotechnical engineering concepts, enabling effective collaboration with engineers to deliver stable and resilient structures.
