摘要
"成冰"公式广泛应用于人工地层冻结法的冻土帷幕平均温度的计算,为了确定"成冰"公式的适应性,本文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,考虑了影响人工冻土冻结温度的定量、定性因素,运用数学理论,分析了"成冰"公式在人工地层冻结中计算平均温度的适应性。结果表明,"成冰"公式不适合用于冻土帷幕平均温度的计算。
"Chengbing" formula is widely applied in the calculation of the average temperature of frozen soil wall in artificial ground treezing. In order to determine the adaptability of the formula, the characteristics of"Chengbing" formula arc an al yzed based on the Bakholdin (Бахолдин) analytical solution of the temperature field, using mathematical theories, with different influencing factors considered. The results of the analy- sis show that "Chengbing" formula is not suitable for the calculation of the average temperature of the frozen soil wall.
