Course Title: Retaining Wall Design and Slope Stabilization Techniques

Delivery Method: Live

Course Description: This 6.5 hour live lecture presentation examines retaining wall loads, forces and stability, slope stability theory, techniques and monitoring, and the principles of biotechnical slop stabilization.

Learning Objectives: 

Learning Objective 1:
Learners will be able to discuss the loads and forces that act on retaining walls, including lateral earth pressure, water pressure, surcharge and traffic loading, and seismic loading.

Learning Objective 2:
Learners will be able to identify and describe types of stability of retaining walls and their applications, including conventional gravity walls, segmental retaining walls, MSE, cellular confinement walls, cantilevered walls, and sheet pile walls.

Learning Objective 3:
Learners will be able to evaluate common slope failures and be able to suggest appropriate techniques to stabilize the failure, including unloading, drainage, buttressing, or reinforcement methods.

Learning Objective 4:
Learners will be able to discuss the principles, advantages, drawbacks and challenges of biotechnical slope stabilization, which uses live and dead plant material.
