Course Title: Texas Retaining Wall Design and Slope Stabilization Techniques
Delivery Method: Live Online
Course Description: This course covers the types of retaining walls and their applications, retaining wall design based on soil parameters, loads and other site conditions, and slope stabilization strategies specific to soils and site conditions found in Texas.
Learning Objective 1:
Learners will be able to differentiate the types of forces that act on retaining walls.
Learning Objective 2:
Learners will be able to describe methods to achieve slope stability, including regrading, slope reinforcement/pinning, ground improvement, retaining structures, and excavation and replacement.
Learning Objective 3:
Learners will be able to identify and explain the features and applications of various types of retaining walls, including cantilevered walls, soldier pile and lagging walls, timber walls, gravity walls, anchored walls, and others.
Learning Objective 4:
Learners will be able to describe the factors that must be considered when designing a retaining wall, including soil design parameters, lateral earth pressure, bearing capacity, settlement, groundwater, backfill and service life.
