| 摘 要： | 从渗流和渗漏情况下堤坝温度场特征、温度场示踪基本原理，分析了影响钻孔温度分布的因素。对实际问题进行合理假设和科学简化，运用稳定热传导理论，把集中渗漏通道简化为圆管状并作为模型边界条件．建立了二维堤坝管状渗漏温度场示踪模型。利用测井温度曲线的最大异常温度，该模型可以计算渗漏通道的位置、渗漏通道大小、流速等参数．工程实例表明，对于垂向流速较小的地下水渗漏进行温度场示踪是有效的方法。

| Abstract: | According to the features of dam temperature field nndcr seepage or leakage conditions and evaluate the influence factors of temperature distribution of drill hole are evaluated. Reasonable assumption and scientific simplification to real problems are carried out. Tracing model of two-dimensional dam piping seepage temperature field is established, by applying steady heat conduction theory and simplifying centralized seepage piping into round piping as the boundary condition of the model. The model can calculate factors of place and size of piping and flow in accordance with maximum abnormal temperature field tracing is an effective measure to trace temperature. It is confirmed by the practical cases that gruundwater seepage with vertical small flow. |
