TVA Monograph No. 75, Chapter 5: Design

This is the core design chapter. It traces the development of cellular cofferdams and sets out the fundamentals of design, including sliding resistance, overturning, shear, interlock tension, fill pressure, and the role of berms.

It then gives the design procedure for cofferdams with and without berms and works through design examples. It closes with examples of actual cofferdam designs used on TVA projects.

In this chapter

• The Development of Cellular Cofferdams
• Fundamentals of Design
• Berms
• Construction Features Affecting Design
• Design Procedure
• Design Example
• Examples of Actual Cofferdam Design Used on TVA Projects
