低温热虹吸管群加固寒区建筑地基的分析计算

Analysis and calculation of reinforced structural foundation in frozen areas with thermosyphon

通过理论分析和数值模拟的方法计算了在不同排列形式下,低温热虹吸管群的传热能力和地基土体温度场.分析结果表明:在其它工况相同的条件下,不同的排列形式会引起单根热虹吸管传输功率的变化,从而对地层的温度场(既加固效果)产生影响。研究结果对寒区工程地基加固时的热虹吸管排列优化有一定的意义。

Analysis and simulation was presented to calculate the capacity and temperature field of thermosyphons group in various arrangements. The result shows that the different arrangements lead to the different heat transferring capacity of a single thermosyphon and influence the underground temperature （the effect of reinforcing）. The result can be used in the arrangement with optimized thermosyphon group in frozen areas.
