摘要: 本文对伊图里河科研楼的四年观测资料分析得出:该楼地基多年冻土在逐年退化。为了保证其地基地温的稳定,提出了将不通风式改为通风式或加大保温层的意见,使该楼基础达到稳定之目的。

Abstract: The building investigated is located in permafrost area of Yitulihe on northwest slope of Da Hinggan Ling, and is the one with raised and unventilated pile foundation. After 4 years’ operation permafrost under the building degradated. Permafrost table descended 1.7 m in 3 years.To ensure the stability of the building, it is suggested that the raised and unventilated foundation must be changed to ventilated one, or the insulation layer must be thickened in order to prevent permafrost degradation.

Key words: raised and unventilated foundation, permafrost degradation, permafrost table
