摘要
基于浅层土体水分场、温度场、应力场和位移场的相互影响,对水热力耦合问题在黄土、冻土、膨胀土、土壤学等领域的研究意义进行了阐述,并对水热力耦合在上述领域研究现状作了回顾和总结。进一步分析了水热力耦合作用机理性研究的不足,指出:通过水热力耦合作用机理性研究确定水热力耦合参数及变量,应是现时进行水热力耦合研究的中心问题。
Taking the influence each other among the moisture field, thermal field, stress and deformation field of soil body into account, the necessity of research on coupled heat-moisture-stress issues about loess, amargosite, frozen soil and pedology is explored. Then the research progress in the issues is reviewed and summarized. After that based on the analysis of the research work up to now, the weakness of mechanism research of soil coupled heat-moisture-stress issues is revealed; and it is pointed that defining the coupled parameters should be the heart of the matter.
