摘要

Effects of heating on promotion of peat consolidation are presented based on a variabletemperature oedometer test on peat, in which peat under creep is rapidly heated and allowed to be settled for a certain period of time, and then later cooled down to the former temperature. Soil temperature was controlled by immersing the consolidation cell in a water bath. Vertical stress was maintained constant throughout the course of heating and cooling. From the test results, it was confirmed that the rate of settlement of peat in the range of secondary compression was increased drastically by heating. Effect of heating on settlement promotion is incredibly larger for peat than for clay. Time - settlement response during heating phase could be approximated by a hyperbolic curve. After cooling the specimen, resettlement followed by small rebound was observed. The rate of resettlement, however, was so small that the long term compression tendency of peat could be reduced upon cooling.
