Artificial frozen soil curtain has promising application prospects. Studies show that the uniformity and frozen permafrost are important impact indicators of artificial frozen soil curtain strength. Frozen direction,force direction, freezing fronts development condition under freezing time and tem-perature law are the four important characteristics of the mechanical property variety of frozen soil. Through analysis on these indicators and characteris-tics, the calculation content of artificial frozen soil curtain is improved for verifying the accuracy of freezing time,freezing location and other important project indexes.%人工冻土帷幕具有广泛的应用前景.研究表明,冻土的均匀性和冻结状态是影响人工冻土帷幕强度的重要指标.冻结方向、受力方向、冻结时间影响下的冻结锋面发展情况和温度场规律是描述冻土力学性能差异的四个重要特征. 该文通过分析这些指标和特征,完善了人工冻土帷幕的分析计算内容,有助于验证冻结时间、冻结位置等重要工程指标的正确性.
