青藏铁路建设中的冻土工程问题

Permafrost Engineering in Qinghai-Tibet Railway Construction

介绍青藏铁路冻土工程的主要特点,阐明解决冻土工程问题的核心是控制融沉和冻胀变形。在总结42年以来冻土工程的科学研究成果和试验工程的研究成果的基础上,提出冻土工程设计、施工的指导思想及施工管理思路,并对未来施工和运营期间的工作进行展望。

The paper briefs on the features of Qinghai-Tibet Railway permafrost engineering andclaries the control of thaw deposit and frosting heaving deformation as the core of thepermafrost engineering. On the basis of scientific research achievements on permafrostengineering and trial project over the past 42 years, it further proposes the envisaging ofpermafrost engineering design, construction instruction and management. The paper alsointroduces the prospect of the future construction and operation work.
