摘　　要：人工冻结温度场巴霍尔金模型已被较为广泛地应用于人工地层冻结法的监测数据分析和冻土帷幕性状的评估中。为了全面评判巴霍尔金模型描述实际温度场的准确性,以温度场数值模拟结果为基础,对单排管和双排管冻结条件下的温度场进行全面的数值分析与巴霍尔金理论的对比性研究。结果表明,对于工程实际应用来说,巴氏模型足够精确,能够较为全面真实地反映人工冻结温度场情况。Bakholdin model is widely applied to the analysis on monitoring data and the evaluation of frozen soil wall character in artificial ground freezing method. In order to evaluate precision for temperature field of artificial ground freezing of Bakholdin model, in the situation of and single - row pipes double - row pipes a full comparative study is made on temperature field between numerical analysis and Bakholdin theory. The results indicate that in practical engineering the application of Bakholdin model is precise enough and can really reflect the temperature field of artificial ground freezing.
