| Abstract: | The building investigated is located in p'ermafrost 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. |
