摘　　要：以基于巴霍尔金温度场理论的冻土帷幕平均温度计算方法为基础,考虑了冻结管间距和冻土半径,得到了平均温度简化公式。同时,用Matlab软件拟合简化公式,得到了简化公式的两个参数。结果表明,采用简化公式计算的平均温度比较接近精确值。The average temperature of frozen soil wall is an important parameter in artificial ground freezing.Based on Bakholdin（ Бахолдин） analytical solution of the temperature field,with the space between freeze pipes and the frozen soil radius considered,a simplified formula for average temperature is established in this paper.At the same time,two parameters for the simplified formula are obtained after fitting the formula with Matlab software.The results of the analysis show that the average temperature calculated by the simplified formula is close to the exact value.
