| Abstract | Instrumentation of a buried warm-oil (71 degrees C) pipeline test section near Inuvik, N.W.T. was undertaken by Mackenzie Valley Pipeline Research Limited, with technical assistance from the Division of Building Research, National Research Council, Canada. The test section was placed in a gravel fill overlying an ice rich silt subgrade. Pore pressures in the resulting thaw bulb were measured using pneumatic piezometers and the rate of movement of the thaw bulb was determined using thermistor probes. Settlements occuring within the fill were measured and correlated with predictions made from laboratory thaw-settlement tests. As a result of this investigation a temperature buildup from 38 to 60 degrees C over a 5-year period is proposed for a full- scale pipeline operation to ensure adequately low pore pressures and to decrease the settlement rates. |
