Course Title: Internal Design of MSE Walls and Geosynthetics
Delivery Method: Live Online
Course Description: This three hour course will cover the design of and materials used in the construction of mechanically stabilized earth (MSE) retaining walls. It will examine geosynthetics, wall properties, code requirements, equations and calculations, and case histories of MSE failures that highlight what NOT to do.
Learning Objective 1:
Learners will be able identify and describe the materials that are used in the construction of a MSE wall, which include geosynthetics.
Learning Objective 2:
Learners will be able to compare geosynthetics that are used in MSE walls by cost, strength and applications.
Learning Objective 3:
Learners will be able to describe how MSE walls interact with other site features such as buildings and utilities, and they will be able to discuss the effects of water on the design and stability of the wall.
Learning Objective 4:
Learners will be able to work with calculations for internal stability of a MSE wall and be able to reference and understand code requirements for MSE walls.
