摘要 为了探寻实际工程中能源桩桩周土壤地下水渗流对能源桩传热性能和热-力耦合特性的影响,建立了考虑地下水渗流的能源桩热-力耦合数值模型,探讨了夏季工况下地下水渗流对能源桩热力学性质的影响。结果表明:夏季工况下能源桩在60 m/a水平渗流场作用下的换热量相对于无渗流情况可增加1.34倍,桩体温升可降低9.12%,地下水的流动降低了桩体位移、桩体轴力、侧摩阻力的变化幅度,还使得能源桩可以更快地达到稳定运行工况;在地下水渗流的影响下,渗流上游的土壤热影响范围明显缩小,但渗流下游的热影响范围显著扩大。

Abstract:The effects of groundwater seepage on the heat transfer and thermo-mechanical coupling characteristics of an energy pile were analyzed using a coupled thermal-mechanical numerical model of the energy pile with seepage. The model shows how the groundwater seepage affects the thermodynamic properties of the energy pile during summer. The results show that in the summer mode the heat transfer of the energy pile with a horizontal seepage velocity of 60 m/a is 1.34 times larger than without seepage. The temperature rise in the pile is then reduced by 9.12%. The groundwater seepage reduces the variations of the pile body displacement, axial force, and the pile side friction while the energy pile rapidly becomes stable. In addition, the groundwater seepage reduces the effect of soil heat in the upstream seepage, but increases the influence of the soil heat in the downstream seepage.
