Abstract
The observed responses during the staged construction of an unreinforced section and a reinforced section of a breakwater founded on soft sediments are presented. Both sections were instrumented and the unreinforced section approached instability at the end of Stage I construction. A series of Class 'C' predictions were made with three different analytical methods. It was particularly difficult to predict the impending instability of the unreinforced section. A fully coupled finite element analysis, with close modelling of the construction sequence and using a strain softening model for the foundation clay, was needed to predict all the observations.

Behavior of a Breakwater on Soft Sediments – Failure and Success
St. Louis, Missouri
The observed responses during the staged construction of an unreinforced section and a reinforced section of a breakwater founded on soft sediments are presented. Both sections were instrumented and the unreinforced section approached instability at the end of Stage I construction. A series of Class 'C' predictions were made with three different analytical methods. It was particularly difficult to predict the impending instability of the unreinforced section. A fully coupled finite element analysis, with close modelling of the construction sequence and using a strain softening model for the foundation clay, was needed to predict all the observations.
