中文摘要：

渗漏是堤坝破坏主要形式之一，只有确定渗漏发生的确切位置和集中渗漏通道的大小和强度，才能对其有效治理。本文基于渗流和渗漏情况下堤坝温度场特征及温度示踪基本原理，对复杂的实际问题进行科学简化合理假设，把集中渗漏通道简化为圆柱状并作为边界条件，结合钻孔探测温度实际，运用稳定热传导理论，建立了圆柱状堤坝渗漏温度示踪模型。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。工程实践表明，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。

英文摘要：

Based on the explicitly discussion laws of temperature field distribution in normal seepage soil in which when leakage occurs, temperature field tracer model is established according to stable heat transmission theory in which intensive seepage passage is reduced to circular pipe, circular pipe and the temperature values from detecting well are treaded as boundary conditions. Location, scale, velocity and temperature gradient of leakage passage are analytically estimated by using this model with a map of temperature field distribution based on temperature values from detecting well. A case study indicates the model is effective when the vertical flow velocity is low. Further research is also presented to solve the imperfection with this model.
