利用线热源法研究堤防集中渗漏通道

Using line-heat-resource method to study concentration leakage passage of dike

从地下水温度场的分布情况来研究堤防的集中渗漏通道,分析了钻孔中地下水温度分布规律,将地层中集中渗漏通道看作线热源,建立线热源法模型.具体以江都高水河船厂段的渗漏研究为例,证实了集中渗漏通道确实存在.

Based on the temperature distribution of groundwater, the concentration leakage passage of dike is studied. From the temperature distribution in borehole, the lineheatresource model is established with regarding the concentration leakage passage as line heat resource. As example, the leakage of Gaoshuihe dike in Jiangdu is studied. The concentration leakage passage is proved to exist.
