中文摘要：

中国多年冻土和季节冻土面积分别占国土面积的21．5％和53．5％。在这些地区，地表层都被一层冬冻夏融的冻结一融化层覆盖，作为地基的冻结一融化层，在其冻融过程中土体性质受气温的变化直接影响着上部建筑物的稳定与安全，因此，在冻土地区进行水利工程、工业与民用建筑及交通运输工程的建设，就必须对冻土及其与工程建筑物相互作用的一系列工程冻土学理论和实践问题做出解答，以确保冻土地基上工程建筑物的稳定性、耐久性及经济合理性。简要回顾了中国冻土力学的创始和发展过程，阐述了冻土力学在强度与变形、本构模型研究、水热过程研究、冻土与结构物相互作用研究及冻土力学测试技术的发展等5个方面的成就，并根据冻土力学学科特点、工程建设对冻土力学发展的要求以及相关学科的发展趋势，展望了冻土力学未来的发展方向。

英文摘要：

China has a land area of 2.15 million km2 covered by permafrost and is named as a third permafrost giant in the world, but it is relative later to systemati,cally study the permafrost, especially the frozen soil mechanics. Since the 1950s, many studies have been carried out to investigate the characteristic of frozen soils for the economic and social development in permafrost regions. The achievements of the frozen soil mechanics in the stress-strain relationship, constitutive modeling, thermal-moisture process, frozen soil-st：ructure interaction and test methods in China are reviewed, and the development trend for studies on the frozen soil mechanics study is predicted according to its subject characteristics, construction demand and the development trend of related subjects.
