摘　　要：通过对俄罗斯西伯利亚铁路和贝阿铁路冻土工程的现场考察以及多次中俄冻土技术交流,对多年冻土工程技术的认识进一步深化。根据俄罗斯多年冻土铁路工程建设情况,阐述贝阿铁路多年冻土工程的主要设计原则和工程措施,分析其多年冻土路基病害状况和主要成因,介绍针对多年冻土病害整治开展的各项研究试验,并对气候变化条件下青藏铁路需要研究和探索的问题提出建议。The understanding of permafrost engineering technology is further deepened through site investigation in permafrost engineering of the Trans-Siberian Railway and Baikal-Amur Mainline in Russia and exchanges on permafrost technology between China and Russia.Based on the construction on the permafrost of the Trans-Siberian Railway and Baikal-Amur Mainline,the main design principles and measures for construction on the permafrost of the Baikal-Amur Mainline are described,the status and main causes of damages to subgrade on permafrost are analyzed,research and tests for treatment of permafrost damages are introduced,and suggestions are put forward on issues of Qinghai-Tibet Railway which need to be studied and explored in the context of climate change.
