摘要: 冻融循环是冻土区埋地管道主要的安全隐患,它不仅给管道带来额外的应力,而且会改变地形结构特殊区域原有的地质特性,在特定的条件下造成地质灾害的发生。系统研究了因冻土融化而产生的冻融滑坡给管道应力带来的影响,而且分析了不同位置的轴向滑坡对管道应力的影响。通过模拟分析可知,不同位移的轴向滑坡对管道应力产生的影响差异很大;改变滑坡的位置,对管道的应力也会产生较大的影响。对受冻融滑坡影响的管道进行的模拟分析结果,可很好地反映应力变化情况,可为冻土区埋地管道的施工建设提供理论依据。

Abstract:

The freezing-thawing circulation was the most common security problems of buried pipeline in permafrost regions, and it could make pipeline generate additional stress. For the regional with the special structure of topographic, the freezing-thawing circulation would change the original geological characteristics, and caused geological disasters under certain conditions. The stress impact of the pipeline was studied generated by the freezing-thawing landslide because of the melting permafrost. The degree of influence of axial landslide with different displacement on the pipeline was analyzed. The simulation analysis showed that different forms of landslide generated a great impact on the pipelines; furthermore, the effects of stress on the pipeline had a greater impact by changing the location of the landslide. The influence on the pipelines generated by the freezing-thawing landslide were simulated and analyzed ,which could well reflect the changes in stress and provide a theoretical basis for building construction of buried pipelines in the permafrost regions.

Key words: Permafrost regions, Buried pipeline, Stress of pipeline, Freezingthawing landslide, Numerical calculation
