地温测定装置调试与分析——以黑龙江大学试验场5 m地温链为例

Debugging and analysis of ground temperature measuring device——A case study of 5 m geothermal chain in Heilongjiang University

地温是重要的气象参数,也是引起天气变化的主要因子,是地表面和地面以下不同深度处土壤温度的统称。地温测定装置可以完成在高寒区地表以下5m地温的测定,对于地温年变化的测量具有重要意义。在判断安置要求并完成装置安装选址后,成功完成了地温链测定装置的安装与调试,使其正常工作,能够稳定接收到数据并且对采集到的数据进行具体分析。本文详细地阐述了地温测定装置的安装与调试过程、注意事项、容易出现的问题以及问题的解决方案,并且对采集到的数据进行潜在误差分析。分析表明装置的安装与调试过程不够完善会极大地影响地温数据,文中叙述的地温测定装置的安装与调试方法可为其他地区安装同类装置提供参考借鉴意义。

Ground temperature is an important meteorological parameter and the main factor that causes the change of weather. It is the general term for the soil temperature at different depths below the ground surface and ground surface. The geothermometer can be used to measure the ground temperature 5 meters below the ground surface in cold region, which is of great significance for the measurement of the geotherm annual variation. After making the placement requirements and completing the site selection of the device, the installation and debugging of the ground temperature chain measuring device were completed successfully, which made it work normally, received the data stably and analyzed the collected data in detail. The installation and debugging process of the geothermal measuring device, precautions, probable problems and solutions to the problems are described in detail, and potential error analysis is performed on the collected data. The analysis shows that the installation and debugging process of the device is not perfect enough to greatly affect the ground temperature data. The installation and debugging method of the ground temperature measuring device described in this paper can provide a reference for the installation of similar devices in other regions.
