ANALYSIS OF A HIGH CRIB WALL FAILURE

A SECTION OF A CRIB WALL, 34 FT HIGH AND CONCAVE IN PLAN, EXPERIENCED SUCH SEVERE DEFORMATIONS THAT IT HAD TO BE DEMOLISHED AND REBUILT. A STUDY SHOWED THAT THE CENTRAL ONE OF THE THREE LONGITUDINAL FOOTINGS WHICH SUPPORTED THE SKELETON OF THE CRIB HAD SETTLED MORE THAN THE OUTER ONES. THIS REVERSED THE USUAL DIRECTION OF THE WALL FRICTION ALONG THE REAR FACE OF THE UPPER SINGLE CELL PART OF THE WALL, REDUCING THE FACTOR OF SAFETY AGAINST SLIDING ALONG ITS BASE TO AN UNSAFE VALUE OF 0.95, AS COMPARED TO THE 2.82 VALUE COMPUTED FOR A CONVENTIONALLY DIRECTLY WALL FRICTION FORCE. /LCPC/RRL/A/
