A literature and design review of crib wall systems

This report reviews the design, construction, and performance of crib wall systems. The two main approaches to analysis, ie Monolith theory and Silo theory, are examined in detail and analogies with infilled cofferdams are also explored. The review of the methods used to assess the stability of crib walls and the loading on individual elements of the crib recommended the use of a limit value approach to design. A step-by-step approach to the design of crib walls is provided and modifications to take into account particular features of construction are considered. Methods and specifications for the manufacture of the crib elements and construction procedures are discussed, and general construction details are reviewed. (A)
