冻结法是有效穿越不稳定岩土层的施工方法，但是对白垩系地层的岩石在冻结过程中的特性研究还不成熟，所以，开展冻结壁岩石在冻结过程中的温度场、水分场以及应力场的研究，对白垩系地层岩石的物理力学特性研究和工程应用都具有重要的意义。 本文以新庄煤矿风立井的冻结工程为背景，在理论上对冻结壁的温度场、水分场、应力场进行分析。论述了温度场的基本概念和影响因素、水分迁移的原理和驱动力以及应力场的相关概念，并且讨论了岩石的物质组成、水分、温度、应力之间的相互作用机理。通过现场监测，得到了冻结壁形成过程中测温孔的温度变化规律、外井壁混凝土水化热对冻结壁温度场的影响以及冻结压力的变化规律。 采用有限元软件ANSYS，对冻结壁的温度场、应力场进行模拟，得到了冻结壁温度、应力分布规律，以及水化热对冻结壁温度场的影响规律。对比分析实测和模拟数据，发现：冻结壁温度场的变化可以分为初始冻结阶段、积极冻结阶段、维护冻结阶段；混凝土水化热对冻结壁的影响深度在1.5米以内；粗粒砂岩的热传导性大于中粒砂岩；温度梯度作用下的水分迁移是导致实测温度值不同于模拟温度值的主要原因；冻结压力在外井壁浇筑完成后迅速增大，随着外井壁强度增大以及冻结壁应力的释放，冻结压力增长速率减小，并趋于稳定。

Freeze method is effective constructiom method of through the unstable rock and soil layer, but the properties research of cretaceous stratum rock in the freezing is not ye mature therefore, to carry out the study temperature field, moisture field, stress field of frozen wall’s rock in the process of freezing has the vital significance for the study of cretaceous stratum rock properties of physical and mechanical and the actual engineering application. The article based on the frozen engineering of Xin Zhuang coal mine wind shaft, analysis the temperature field, moisture field, stress field of frozen wall from theoretical. Discusses the basic concept and the influence factors of temperature field, the principle and driving force of moisture migration as well as the related concepts of stress field, and discussed the interaction mechanism of rock composition, moisture content, temperature and stress. Through field monitoring, getting the thermometer hole temperature change rule in the forming process of frozen wall, the influence law of the hydrated heat from the concrete shaft liner to the frozen wall temperature field, and the changing regularity of freezing pressure. Using finite element software ANSYS simulate the temperature field, stress field of frozen wall and get the distribution law of temperature, stress of frozen wall, as well as the influence law of the hydrated heat to the frozen wall temperature field. Comparative analysis of the measured and simulated data can get the following conclusion: the change of the frozen wall temperature can be divided into initial stage of freezing, positive stage of freezing, maintenance stage of freezing; the influence depth is 1.5 meters of the hydrated heat for the frozen wall; the thermal conductivity of coarse grained sandstone is greater than medium grained sandstone; the moisture migration under the action of temperature gradient is the main reason of measured temperature value different from simulated temperature value; frozen pressure increases quickly after the completion of concrete shaft liner, with the strength increase of shaft liner and stress release of frozen wall, the growth rate decreases freezing pressure and tends to be stable.
