在国家自然科学基金及冻土工程国家重点实验室基金资助下，项目组与俄罗斯和日本学者合作，从土体冻胀和盐胀的基本影响因素及其相互关系、土中水的成冰作用和冷生组构、土体冻胀机理及含盐土的盐胀和冻胀等方面，对土体冻胀和盐胀机理进行了深入研究，提出许多全新的观点... Supported by the National Natural Science Foundation of China and the State Key Laboratory of Frozen Soil Engineering, the project team cooperated with Russian and Japanese scholars. From the basic influencing factors of frost heaving and salt expansion and their interrelationships, And cold formation, the frost heave mechanism of soil and the salt expansion and frost heave of saline soil, the mechanism of frost heaving and salt expansion in soil is deeply studied and many new ideas are put forward.
