| Abstract: | The thermosiphon is a refrigerating installation, which can control and retard the melting rate of the frozen earth, and then lower the destructive effect from the frost heaving on the railway bed, so as to get the target of stabilizing the railway bed constructed through the permafrost region, when it is applied to the permafrost, especially the frost earth in the permafrost region with high ice content. |

| Keywords: | thermosiphon frost earth with high ice content effective heat transfer radius, frost index frost radius Qinghai-Tibet Railway |
