基于双U管的热响应试验与室内瞬态法试验的差异分析

DDifference analysis of thermal response tests based on double U-tube and indoor transient test

由于含水率变化等原因,可能使实验室所测数据与实际土壤情况相比发生了改变,因此所测结果有可能并不能准确反映地下岩土的真实情况。因此,本文利用工作区内已做的8个基于线热源模型数据处理的热响应试验孔所测试的数据结果与实验室采用瞬态法测试的165件热物性测试样品数据进行差异分析,量化分析其差异规律性,为参数的准确性与可靠性提供数据支撑。

Due to changes in water content and other reasons,the data measured in the laboratory may differ from the actual soil conditions,which leads to the fact that the measured results may not accurately reflect the actual situation of underground rocks and soils.Therefore,this paper quantitatively analyzes the regularity of differences by comparing the test results of 8 thermal response tests based on the linear heat source model from the working area with the thermal physical test data of 165 samples tested by the transient method in the laboratory,in order to provide data support for the accuracy and reliability of parameters.
