Summary

THIS PAPER PRESENTS THE RESULTS OF A COMPARISON OF SEVERAL MOD ELS DESCRIBING THE THERMAL BEHAVIOUR OF A SOIL AROUND A BURIED COLD PIPE AND THE CONFRONTATION OF CALCULATIONS WITH MEASUREMENTS MADE IN A PILOT STATION. A TWO-DIMENSION THERMAL MODEL OF STATIONARY CONDITION IS USED FOR DETERMINING THE EQUILIBRIUM POSITION OF THE 273 K (0 DEG C) ISOTHERM WITHOUT ALLOWING FOR THE CHANGE OF PHASE. AN AXISYMMETRICAL SINGLE-DIMENSION MODEL DEALS WITH THE PROBLEM OF CHANGE OF PHASE UNDER TRANSIENT CONDITIONS AND APPEARS VERY CONVENIENT FOR DESCRIBING THE PHENOMENON IN A WIDE RANGE OF GEOMETRICAL AND THERMAL CONDITIONS. A SOPHISTICATED TWO-DIMENSION MODEL IS USED AS A REFERENCE TO DETERMINE THE LIMITS OF THE DOMAIN OF USE OF THE AXISYMMETRICAL MODEL.
