【摘要】：中俄輸油管線約有510公里穿越我國(guó)大興安嶺多年凍土地區(qū),其沿線的多年凍土在氣候條件、自然地理及人類活動(dòng)等多方面因素影響下融沉性也有一定差異,由此產(chǎn)生的差異性沉降將對(duì)管道的安全運(yùn)營(yíng)造成威脅。本文通過(guò)分析對(duì)比研究中俄輸油管線沿線多年凍土融沉的影響因素、融沉量的理論計(jì)算與野外實(shí)測(cè)值,提出中俄輸油管線沿線多年凍土的主要融沉特征,對(duì)多年凍土區(qū)的工程建設(shè)、運(yùn)營(yíng)維護(hù)具有重要的理論與實(shí)際價(jià)值。
[Abstract]:The Sino-Russian oil pipeline passes through permafrost regions of Daxing'anling in China about 510 kilometers. The permafrost along the pipeline has some differences in thawing settlement under the influence of climatic conditions, natural geography and human activities, etc. The resulting differential settlement will pose a threat to the safe operation of the pipeline. By analyzing and comparing the factors affecting thawing settlement of permafrost along Sino-Russian oil pipeline, the theoretical calculation of thawing volume and the field measured values, the main thawing characteristics of permafrost along Sino-Russian oil pipeline are put forward in this paper. Operation and maintenance have important theoretical and practical value for engineering construction in permafrost region.
