The recent advances in frozen soil mechanics are demonstrated and discussed from four aspects: (1) Test studies on the mechanical properties of the frozen soil; (2) Heat conductivity properties of the mixture materials of the freezing soil; (3) Water migration behaviors in the freezing soil; and (4) The Heat-Moisture-Deformation Coupling Models.

从冻结土的宏观力学性质，正冻土中的水、热迁移理论，正冻土的水热力耦合模型四个方面分析综述了国内外冻土力学的发展历史、研究现状与我国冻土力学研究中存在的问题，指出：（１）当前冻土力学的研究内容应该从对冻结上的宏观强度与变形性质向更切合实际工程需要的正冻土、正融土微、细观热、力学耦合性质方面深化；（２）冻土力学的研究思路应该从对土样纯力学量的试验研究向土样组构、级配、含水量、饱和度等土性指标在不同负温下对土样颗粒排列与胶结特性的强度、变形影响机理方面转移；（３）冻土力学的研究对象也应该从室内冻结试验的研究向具有各种不同水热交换边界条件与水热迁移内在规律的冻土体发展。
