Equivalent parabolic arch method of average temperature calculation for straight double-row-pipe frozen soil wall
Abstract：A new method of calculating the average temperature of double-row-pipe frozen soil wall was proposed.This new method,namely the equivalent parabolic arch method,is based on the Bakholdin（Бахолдин） analytical solution of the temperature field for the double-row-pipe frozen soil wall and a modified solution considering the actual freezing temperature of the soil.The average temperature of the whole frozen wall was presented by the average temperature along thickness on a certain cross section and this temperature was calculated by the equivalent parabolic arch method.Within the possible range of the freezing pipe layout parameters for the practical engineering conditions,a comprehensive error analysis was carried out comparing the average temperature calculated by the equivalent parabolic arch method with that calculated by numerical integration of the Bakholdin analytical solution.The results demonstrate that the average temperature produced by the equivalent parabolic arch method bears favorable accuracy for engineering practice.
