【摘要】 针对理论研究和冻结工程的实际需要,首先分析了土体冻结过程中温度、应力、水分场耦合原理,并按照冻土体形成发展过程,其次建立了单一冷源冻结轴对称温度、应力、水分场耦合模型；随后,应用势场叠加原理,将单一冷源情况下的三场耦合问题推广至多冷源情况下的三场耦合；最后给出了一个隧道冻结工程算例,并提出了几点结论和看法。更多还原

【Abstract】 According to the requirement of theoretical study and engineering practice,the coupling principle of three fields is analyzed in the article.Then,the coupling model of single freezing pipe axial symmetry of temperature,stress field and moisture migration is put forward.Thirdly,by means of the progressing principle of potential field,the coupling model of three fields which is under the condition of the multi-freezing pipes is extended.Finally,a example,several proposals and suggestions are given.更多还原
