摘要：

为深化对地铁隧道热环境与围岩之间关系的认识,通过理论计算得到各季节围岩换热量作为间歇性热源边界对围岩进行加热,以模拟围岩和隧道热环境的动态变化,将其作为数值模型的热边界条件,建立三维地铁隧道围岩温度场模型,并与实测数据进行了对比. 结果表明,模拟结果与实测数据吻合较好,验证了该模型的可靠性.利用该模型对比分析了换热器对地铁区间隧道围岩长期温度场演化规律的影响. 换热器在夏季能有效减小围岩温度的变化幅度,提高围岩的蓄热能力;在冬季能使围岩储存更多冷量,并可部分抵消区间隧道在下一年产生的热量,从而改善围岩的蓄冷能力.

In order to deepen the understanding of the relationship between the thermal environment andsurrounding rock of subway tunnels, the heat transfer of surrounding rock in each season was calculatedthrough theoretical calculations as an intermittent heat source boundary to heat the surrounding rock, tosimulate the dynamic changes of the thermal environment of the surrounding rock and the tunnel. As thethermal boundary condition of the numerical model, a three-dimensional temperature field model of thesurrounding rock of the subway tunnel is established and compared with the measured data. The resultsindicate that the simulation results are in good agreement with the measured data, verifying the reliabilityof the model. The influence of heat exchangers on the long-term temperature field evolution ofsurrounding rock in subway tunnel sections was compared and analyzed using this model. Heatexchangers can effectively reduce the amplitude of temperature changes in the surrounding rock duringsummer and improve the heat storage capacity of the surrounding rock. In winter, it can store more coldenergy in the surrounding rock and partially offset the heat generated by the interval tunnel in the nextyear, thereby improving the cold storage capacity of the surrounding rock.
