建立了岩土热响应测试的三维数值分析模型,分析了不同情况下地上换热对岩土热响应测试结果的影响。结果表明;在相同条件下,埋管深度越小,地上换热引起岩土热响应测试结果的误差就越大;测试环境空气温度的波动会导致岩土热响应测试结果的波动;在实际工程应用中,可通过抑制载流体与地上环境之间一切形式的换热,来减少岩土热响应测试结果的误差。 A three-dimensional numerical analysis model of geothermal thermal response test was established, and the influence of on-ground heat transfer on geothermal thermal response test results under different conditions was analyzed. The results show that under the same conditions, the smaller the depth of the buried pipe, the greater the error of the test results of geothermal heat response caused by the ground heat transfer. The fluctuation of the test ambient air temperature will lead to the fluctuation of the thermal response of the geotechnical test. In applications, errors in geothermal thermal response test results can be reduced by suppressing all forms of heat transfer between the carrier fluid and the aboveground environment.
