| 摘 要： | 地下水的渗漏会影响地层正常温度分布,使钻孔温度曲线发生异常变化。堤坝的管涌渗漏通道可看作是一个持续作用的线热源,通过研究管涌渗漏水对地层温度的影响,利用热源法的原理建立了管涌渗漏的持续线热源模型。工程实例的计算表明,利用该模型可以得到管涌通道的渗透流速,评价地层的渗漏特性。

| Abstract: | Leakage of groundwater will influence strata normal temperature distribution and generate the abnormality on temperature curve. The piping leakage passage can be regarded as a continuous line heat resource. Through studying the influence of piping water on strata temperature, a continuous line-heat-resource model is proposed by using the heat resource theory. Verified by an example, the model can be used to get the leakage velocity of piping passage and estimate the permeability of strata. |
