Some Strength Properties of Frozen Soil and Effect of Loading Rate.

摘要

The report presents frozen soil strength data for several soil types. The data include the effects of unit dry weight and the degree of saturation on the strength of frozen soils. The frozen soil strength increases with moisture content (frozen) up to full saturation and then drops off at greater ice contents. Data are presented showing that the compressive strength of many materials,frozen (including sea ice) and non-frozen,is greater under rapid loading rates. Fresh water ice shows the opposite effect Values of the adfreeze bond of frozen soils to various materials are also presented. (Author)
