我国建筑工程方面的冻土研究始于1960年左右,回顾三十年来的历程,大体上可分成两个阶段。第一阶段为自1960年到1966年,该阶段由于我国从头开始,参考苏联的已有经验,进行调查研究,然后着重研究地基土的冻胀规律、冻融变形对房屋建筑的危害等。第二阶段从1972年至目前,该阶段是在前段研究的基础上重点解决编制设计规范中所遗留的问题,如房屋基础在冬季所受到的冻胀力大小及计算,以及防治冻胀破坏的有效措施等。当时开展冻土研究工作的单位有中国建筑科学研究院地基研究所(简称地基所)、哈尔滨建筑工程学院、大庆石油管理局油田设计研究院(原石油部第五设 The research on permafrost in the field of construction engineering in China started around 1960. Looking back over the past 30 years, it can be roughly divided into two phases. The first stage was from 1960 to 1966. Since the beginning of the country, with reference to the Soviet Union’s existing experience, it conducted investigations and studies, and then focused on studying the laws of frost heave of foundation soil and the damage of freeze-thaw deformation on building construction. The second stage from 1972 to the present stage, which is based on the previous study, focuses on resolving issues left over from the preparation of design specifications, such as the magnitude and calculation of the frost heaving force of the building foundation in winter, and the prevention of frost heaving damage. Effective measures and so on. At the time, the units engaged in research on frozen soil included the China Academy of Building Research Foundation Institute (abbreviated as Foundation Institute), Harbin Institute of Civil Engineering and Architecture, and the Daqing Petroleum Administration Oilfield Design and Research Institute (formerly the fifth ministry of the Ministry of Petroleum.
