A Study and Analysis of Timber Crib Retaining Walls
Comparisons are made of the various types of highway retaining walls, including the timber crib, with respect to site adaptation, materials, foundation support and economics. Timber crib and other types of walls were visually observed. In the study, earth pressure inside the timber cribs and the resulting stresses in the crib members and connections were calculated using bin pressure theory developed by Janssen. Their resistance to sliding and overturning was determined in the same manner as for other gravity retaining walls. Because of the myriad of natural occurring soils, four hypothetical groups of soils considered suitable for retaining wall cribfill and backfill were used. In order to predict the relative performance of seven different timber crib wall designs, each design was completely analyzed for internal stresses and external stability with each of the four hypothetical soil groups. The backfill geometry was also varied from a level to a sloping backfill. Performance of each of the wall designs was then compared and conclusions were drawn about the characteristics and performance of the various wall designs.
