Combined with an engineering project, this paper uses large-scale finite element software ANSYS to make the structure analysis of indirect air-cooled tower, considering the effect of foundation soil. The distribution characteristics of air-cooled tower's displacement, stress and internal force is focused on respectively under the gravity, temperature load and wind load. The local stability of
