摘 要: | 温度差异是高原冻土地区公路路基发生翻浆的一个重要因子,笔者建立了冻土路基温度传导物理模型,并应用熵的增量论证了路基温度传热方向;运用能量定理,得到了温度场的二维及三维非稳态热量传递数学微分方程.这对翻浆路基的进一步研究有重要的理论意义.

Research on mechanism for temperature to transmit in tympanites roadbed |
| |
Abstract: | The diversity of temperature is an important factor for tympanites to occur in highway roadbed.The physical model of temperature transmitting is founded in this paper.Based on the model,applying increment theory of entropy,the transmitting-heat directions of roadbed temperature get demonstrated.And differential equations of two and three dimensions for unsteady state quantity of heat to transfer are observed in temperature field.It has significant senses for more research of tympanites. |

Keywords: | tympanites frozen soil roadbed roadbed deformation equivalent frozen soil heat exchange radiate |
