【摘要】：中俄输油管线约有510公里穿越我国大兴安岭多年冻土地区,其沿线的多年冻土在气候条件、自然地理及人类活动等多方面因素影响下融沉性也有一定差异,由此产生的差异性沉降将对管道的安全运营造成威胁。本文通过分析对比研究中俄输油管线沿线多年冻土融沉的影响因素、融沉量的理论计算与野外实测值,提出中俄输油管线沿线多年冻土的主要融沉特征,对多年冻土区的工程建设、运营维护具有重要的理论与实际价值。
[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.
