摘要/Abstract

摘要： 冻土力学是冻土工程学的理论基础，以解决冻土工程问题为归宿。冻土力学分为冻土静力学和冻土动力学两个方面，而冻土静力学是冻土力学的重要部分。为此，对常规冻土静力学室内试验的研究进展进行了总结，系统地阐述了其在冻土的强度特性、变形特性及理论模型等方面所取得的重要研究成果，并指出研究中存在的一些不足之处。最后结合冻土静力学研究的特点及实际冻土工程建设的需要，对冻土静力学研究的未来发展进行了展望。

关键词: 冻土静力学, 室内试验, 冻土强度, 变形特性, 研究进展

Abstract: Frozen soil mechanics is the theoretical foundation of geocryology and is the key for solving engineering problems in cold regions. It is necessary to study mechanical properties of frozen soil for the sake of constructions in cold regions, so as to guarantee their stability. The frozen soil mechanics includes the frozen soil statics and the frozen soil dynamics, and its statics plays an important role in the study of frozen soil mechanics. In this paper, the research progress in laboratory test of conventional frozen soil statics is summarized, as well as the studies on strength, deformation and theoretical model. The important role of frozen soil mechanics in cryospheric science and the construction in cold regions is affirmed, and its shortage at present is also pointed out. At last, the development trend for studying the frozen soil mechanics is predicted according to the characteristics of frozen soil mechanics and construction demand.

Key words: frozen soil statics, laboratory test, frozen soil strength, deformation characteristics, research progress
