Abstract:The China-Russia Crude Oil Pipeline (CRCOP), one of the four key national energy strategic channels, plays an important role in ensuring national energy security, diversifying oil supplies and transportation patterns, promoting the China-Mongolia-Russian economic corridor, and deepening Sino-Russian strategic cooperation. Aiming at permafrost engineering problems along the CRCOP, the principles of thaw control are put forward. This study develops a set of innovative techniques for mitigating and controlling the thaw of permafrost foundation soils of the pipeline, which provides an important guarantee for the green construction and safe operation of the CRCOP and can protect the permafrost environment along the pipeline route. The research results can offer important references and basis for design, construction, and maintenance of the similar projects in permafrost regions.
