FREEZING AND CYCLIC TRIAXIAL BEHAVIOR OF SANDS

In order to determine whether the freezing done to facilitate the shipment of undisturbed samples effects the cyclic triaxial behavior of sands, several sand samples, frozen and unfrozen, were subjected to laboratory cyclic triaxial testing. No significant effect from freezing on either specimen density or liquefaction behavior could be established for the sands tested. It is the writer's opinion, however, that those wishing to use freezing as an alternative sample handling must take precautions to assure themselves that freezing a particular sand will not effect its liquefaction behavior. Such precautions might include comparative testing of samples, but in any event should only be attempted with those sands that are relatively free draining. Samples that are not well drained will expand upon freezing with possible severe disturbance. For this reason it is advisable to monitor simple drainage and if samples are frozen, lengths should be carefully monitored, and observations made to detect any volume changes upon thawing.
