But, even the permafrost table has highly raised the annual thermal imbalance of soil and the process of temperature rise, it is disadvantageous for the thermal stability of permafrost
對于高溫多年凍土來說，盡管多年凍土上限也得到了較大幅度的抬升，但升溫過程和土體年收支的不平衡都在朝著不利於多年凍土熱穩定方向發展。 -
And, for cold permafrost, a better thermal stability situation will be developed under the condition that the temperature near the permafrost table beneath the block - stone embankment has largely dropped
然而，對于低溫多年凍土來說，塊石路基下部多年凍土上限附近溫度有了較大的「冷量」積累，多年凍土正在朝著有利於熱穩定方向發展。 -
By comparing and analysing the computed results and the change of the raised permafrost table, a concl usion is gived that the roadbed with insulations on the permafrost protects the permafrost well under itself, and the rational position and thickness for insulation were suggested
通過對計算結果和多年凍土上限變化的分析比較，得出了在多年凍土區路基中鋪設保溫材料對路基面下多年凍土具有明顯的保護作用，總結出在多年凍土區路基工程中鋪設保溫層的合理厚度與位置。
