Abstract:
A study was performed to compile standard timber crib retaining wall designs and design methods and to antytically investigate the behavior of these structures. Cribs were evaluated by studying (a) bin pressures (using the Janssen theory), (b) member stresses, (c) external stability (including lateral earth pressures), (d) differential settlement, (e) drainage, and (f) preservation of timber members. Engineering design criteria were incorporated into a computer program, and the standard designs were analyzed to detect either overstress of the crib members or potential failure of the entire crib due to external stability problems. An extensive literature search was performed, and companies, organizations, and agencies that might have knowledge of and experience with these structures were queried. The study was augmented by extensive field inspection of timber crib retaining walls.
