PHYSICAL MODEL TESTING OF TEMPORAL VARIATION OF SOIL TEMPERATUE IN DEPTH

  • 摘要: 利用自主开发的土体温度物理模型试验系统,研究了土体剖面温度随时间的变化规律,通过改变土体表面的覆盖层属性,对比分析了裸土和混凝土板覆盖下土体剖面的热传递特点。结果表明:在恒定热源作用下,土体剖面温度迅速上升到一定值之后逐渐趋于稳定,初始升温速率随深度的增加而呈指数递减,最终平衡温度随深度的增加而显著衰减; 温度在土体剖面上的传递存在明显的滞后效应; 混凝土板覆盖下土体的初始升温速率和最终平衡温度较裸土高; 土体剖面热通量反映了土体中热量的传递特征,其变化规律与上下土层间的温度差变化规律一致。
