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。
為瞭利用隄壩溫度鑑測得到的溫度場信息反縯齣滲漏通道的流速,對線熱源傳熱模型進行瞭優化,併利用室內試驗進行瞭驗證。結果錶明:優化後的線熱源模型在各試驗工況下的誤差均較小,最大誤差為4.975%,能夠模擬隄壩的實際傳熱狀態。

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.
