摘要
Abstract
Various geophysical methods exist to detect underground heating pipelines,but shallow geothermal measurement is a more straightforward method.Geothermal gradient data obtained by measuring the temperature at different depths underground has the advantage of suppressing the background temperature field and homologous thermal noise.It is suitable for shallow heat source exploration.Based on the Laplace equation of the temperature field,the paper takes the temperature of the observation point directly above the heat source and the temperature of the outer surface of the heat temperature as the boundary conditions.With the newly derived positive formula as the kernel function,the correlation imaging method is used to locate the central position of the heat source.After the theoretical model test and the comparing the measured data processing result of the heating pipeline with its reality position,the advantages and applicability of this method are analyzed.关键词
