摘要
主要阐述我国人工冻结粘土蠕变的物理意义和特征，并将表征这些特征的试验数据进行分析，建立了相应的我国人工冻结粘土蠕变的数学模型，求出对应的蠕变参数。通过在我国特大型矿井济宁二号矿井冻结壁设计中的蠕变计算实例，说明所建立的我国人工冻土蠕变数学模型的正确性及在冻土结构蠕变计算中的应用，为我国人工地层冻结法在各种岩土工程应用中冻土结构蠕变计算奠定了理论基础。
The physical meaning and features of creep of artificially frozen clay in China are mainly described. The test data representing these features are analyzed and based on which, a mathematic model is established correspondingly. And the parameters of creep are also obtained. Calculation of creep of the ice wall for Jining No. 2 mine has proved the correctness of the mathematic model which is applicable to caleulation of creep of frozen clay structure. It has laid a theoretical foundation for creep calculation of frozen soil structures in various geotechnical engineering using freezing method. Shell Coal International.
