基于热传递微分方程讨论了水流导热影响下地温特征与深度的关系,获得地温、地温梯度与深度关系的解析表达;对渗流影响下的地温特征类型进行分析,提出了通过最小二乘法拟合地温试验数据计算渗流参量、获取渗流特征的方法及程序。并以滇西高黎贡山越岭段为研究对象,基于地温特征对其热水渗流分区进行分析。研究认为,穿越其中的拟选隧道线南北两水热活动区相互独立,黄草坝断裂阻隔了北面热水向南面渗流,判定断裂南面区域一定范围为南部热水的补给地带,越岭拟选隧道线为区内低地温通道,为合理规避隧道热害提供了依据。
Based on the differential equation of heat transfer, the relationship between the geothermal characteristics and depth under the influence of water flow and heat transfer is discussed, and the analytical expression of the relationship between the geotemperature and geothermal gradient and depth is obtained. The type of geothermal characteristic under the influence of seepage is analyzed. Experimental data Calculation of seepage parameters, methods and procedures for obtaining seepage characteristics. Taking the Yueling section of Gaoligongshan Mountain in western Yunnan as an example, the sub-region of hot water seepage was analyzed based on the geothermal characteristics. It is concluded that the north-south water-heat activity zones are independent of each other and the Huangcaoba fault blocks the seepage of the north hot water to the south, and the southern zone of the fault ruins the south hot water recharge zone. The tunnel line is a low-temperature warm channel in the area, which provides the basis for reasonable avoidance of tunnel thermal damage.
