中文摘要：能源盾构隧道是开发利用浅层地热能的重要地下结构,但关于地下水渗流对其换热性能影响的研究尚不充分。为此,采用模型试验和数值模拟相结合的方法,系统研究地下水渗流流速和流向对能源盾构隧道换热性能的影响。首先,构建相似试验模型,开展夏季5种工况的模型试验,明确地下水渗流对换热管及隧道围岩温度场分布的影响,并利用试验结果验证数值模拟的准确性;然后,基于不同流速、流向及季节变化条件,进一步开展20种工况下的数值模拟研究。研究结果表明,随着地下水渗流流速的增加,能源盾构隧道换热性能显著提升;渗流方向与隧道轴线间夹角的减小有助于提升换热性能;在夏季工况下,换热管进出口温差显著大于冬季工况。

外文摘要：Energy shield tunnels serve as critical underground structures for exploiting shallow geothermal energy,yet research on the influence of groundwater seepage on their heat exchange performance remains insufficient.To address this,a combined approach of model test and numerical simulation was employed to systematically investigate the effects of groundwater seepage velocity and flow direction on the heat exchange performance of energy shield tunnels.First,a similar experimental model was constructed to conduct model tests under five summer working conditions,clarifying the impact of groundwater seepage on the temperature distribution of heat exchange pipes and surrounding rock.The experimental results were then used to validate the accuracy of numerical simulations.Subsequently,20 numerical simulation cases were performed under varying seepage velocities,flow directions,and seasonal conditions.The results demonstrate that the heat exchange performance of energy shield tunnels significantly improves with increasing groundwater seepage velocity.A smaller angle between the seepage direction and the tunnel axis enhances heat exchange efficiency.Under summer conditions,the temperature difference between the inlet and outlet of the heat exchange pipes is markedly greater than that observed in winter conditions.
