【摘要】：凍融循環(huán)是凍土區(qū)埋地管道主要的安全隱患,它不僅給管道帶來(lái)額外的應(yīng)力,而且會(huì)改變地形結(jié)構(gòu)特殊區(qū)域原有的地質(zhì)特性,在特定的條件下造成地質(zhì)災(zāi)害的發(fā)生。系統(tǒng)研究了因凍土融化而產(chǎn)生的凍融滑坡給管道應(yīng)力帶來(lái)的影響,而且分析了不同位置的軸向滑坡對(duì)管道應(yīng)力的影響。通過模擬分析可知,不同位移的軸向滑坡對(duì)管道應(yīng)力產(chǎn)生的影響差異很大;改變滑坡的位置,對(duì)管道的應(yīng)力也會(huì)產(chǎn)生較大的影響。對(duì)受凍融滑坡影響的管道進(jìn)行的模擬分析結(jié)果,可很好地反映應(yīng)力變化情況,可為凍土區(qū)埋地管道的施工建設(shè)提供理論依據(jù)。
[Abstract]:Freezing and thawing cycle is the main safety hazard of buried pipeline in permafrost area. It not only brings additional stress to the pipeline, but also changes the original geological characteristics of the special terrain structure, and causes geological disasters under certain conditions. The effect of freezing thawing landslide caused by frozen soil melting is studied systematically. The effect of axial landslide in different positions on the stress of pipeline is analyzed. Through the simulation analysis, it is found that the influence of the axial landslide with different displacement on the pipe stress is very different; the change of the position of the landslide will have a great influence on the stress of the pipeline. The simulation analysis results of the pipeline which is affected by the freezing thawing landslide can be very good. Reflecting the change of stress can provide a theoretical basis for the construction and construction of buried pipelines in permafrost regions.
