Abstract:Based on geothermal observation data from 2012 to 2015 in different strata in Huailai, combined with MAPSIS, MapInfo, SPSS and other software to analyze the data, several conclusions can be drawn. Analyzing the east, west, south, north data of the temperature detectors in wells, we can get the approximate position of the hot water pipe nearby. In general, the changing trends of geotemperature in four directions are almost similar. According to the figure of geothermal curve of the multiple depth, combined with the analysis tables, the conclusion could be drawn that under 3.2 meter, the geotemperature near the wells is not affected by the weather on the whole, with only slow annual change. The geothermal curve of 5.0 meter deep is more stable. Considering economy and convenience, the best depth of geothermal observation is 5 meter.
