摘　　要：人工多圈管冻结过程中的温度场、应力场及水分场的相互作用,是一个非线性多场耦合问题,影响因素多.本文以淮南顾北矿作为模型设计原型,通过模型试验对多圈管冻结土体过程的温度场、应力场及水分场变化进行研究,获得了冻结温度场、冻结压力及含水量随冻结时间的变化规律,其成果对建立水热力耦合数学模型提供可靠依据并能更好的指导矿井工程实践.The interaction between the temperature field the pressure field and the moisture field in the multicoil pipe freezing process is a problem of non-linearity and multi-fields, involving many factors. The temperature field, the pressure field and the moisture field in the freezing process are studied by the model experiment based on the Gubei Mine in Huainan, the variations of the temperature filed, the pressure field and the moisture field againt the freezing time are obtained. The results can be used to establish the coupling model of the moister fields, the temperature fields and the pressure fields to be used in mining engineering practice.
