Zusammenfassung:The invention discloses a method for testing the heat transfer property of a high-temperature hot water tunnel concrete material. The method comprises the following steps: S1, mounting a test device; s2, a concrete test piece is manufactured, temperature measuring points are arranged in the concrete test piece and on the upper surface and the lower surface of the concrete test piece, and heat flow sensors are arranged on the upper surface and the lower surface of the concrete test piece; s3, connecting the temperature and heat flux sensor of each measuring point with a data acquisition instrument, and setting an acquisition frequency; placing the concrete test piece with the mold at a reserved position of a water bath box, continuously acquiring data until the data of each measuring point tends to be stable, and acquiring temperature and thermoelectric force data; and S4, according to the data collected in the step S3, calculating various parameters of the heat transfer property of the high-ground-temperature
