Analysis of soil temperature field by revised average constant heat flux method

Revises the average constant heat flux method in order to extend its application scope, and presents the complete method and section method. Combined with practical engineering situations, simulates and compares the soil temperature fields obtained by the two methods. The results indicate that the section method is accurate and reliable to obtain the soil temperature field at any time. The soil temperature fields are almost the same at cycle time point using the two methods. When analysing soil temperature field at cycle time point or conducting a long-time simulation, or when the requirement for data accuracy is not high, the complete method is simple and convenient. Points out the application scope of the two methods.
