Abstract : Considerable frost pressures (averaging 300 to 600 psf) were observed to act on a tie-back excavation bracing system. The resulting horizontal movements were about 0.07 ft. Both pressures and movements were less than those anticipated. Over 50% of the frost pressure appears to have dissipated owing to outward yield of the bracing. The bracing yield in turn appears to have been caused by plastic flow at points of local overstress. (Author)
