中俄原油管线多年冻土融沉特性（英文）

Thawing settlement characteristics of permafrost along China-Russia oil pipeline

中俄原油管道穿过我国大兴安岭多年冻土区约510km。多年冻土区的冻土融沉特性受到气候条件、自然地理、人类活动等因素的影响。多年冻土的融沉将威胁中俄石油管道工程的安全运行。依据研究区多年冻土现场观测资料,通过综合研究,提出了大兴安岭多年冻土区冻土融化沉降特性,为管道项目工程安全运行和维护提供科学方法。

With the length of about 510 km, China-Russia oil pipeline passes through Chinese permafrost in Daxinganling area. The permafrost is different in thawing settlement characteristics under the influences in climatic condition, physical geography, human activities and other factors. Thus the various settlements characteristic will threat to the safe operation of the oil pipeline project. The comprehensive evaluation of the permafrost soil on-site exploration are studied, the major thawing settlement characteristics of the permafrost are summarized and concluded and provided supporting method for operating and maintaining pipeline project in future.
