堤坝渗漏线热源传热模型优化分析

摘要

为了利用堤坝温度监测得到的温度场信息反演出渗漏通道的流速，对线热源传热模型进行了优化，并利用室内试验进行了验证。结果表明：优化后的线热源模型在各试验工况下的误差均较小，最大误差为4.975％，能够模拟堤坝的实际传热状态。%To take advantafe of the temperature field information around the leakafe channel for monitorinf the flow rate in the dam,this paper pro-posed the line-heat-source conductive model by a reasonable optimization and desifned the laboratory tests to verify the theory. The results show that:the optimized line-heat-source model error in each test condition is smaller and the maximum error is 4. 975%. So this method can simulate the actual transfer state of dam.
