For large-scale intercooling towers of the 1 000 MW level

under conditions restricted by layout and complex foundation sit-uations

the use of the type of small-inclination-angle intercooling tower can effectively reduce the land occupation range

and lower the costs of foundation treatment and land acquisition.For a 1 000 MW project that adopted a small inclination angle intercooling tower scheme

conventional reinforced concrete X columns and new steel pipe concrete X columns were designed as two types of inclined column schemes.Analysis and calculation were carried out using SAP2000.The calculation results show that the steel pipe concrete X column scheme has larger overall rigidity of the tower body

stronger load-bearing capacity of the steel pipe concrete X column

fewer X columns

and relatively smaller cross-sections

making it more suitable for the small inclination angle type of intercooling tower.
