Figure 4-47. Frozen soil creep tests, unconfined compression, Manchester fine sand87. Instantaneous strength is
maximum stress determined by loading specimen at a constant strain rate of 0.033/min. Long-term strength is maximum
stress that the frozen soil can withstand indefinitely and exhibit either a zero or continually decreasing strain rate with time.
