[Purposes] The stress characteristics of the Cuojiaotou style cable tower are analyzed to accumulate experience for the design and construction of this type of cable tower structure. [Methods] Taking the Niutianyang Bridge with a main span of 468.00 m as the background, this paper establishes a spatial local finite element model and uses the static analysis and steady‐state thermal analysis methods to study the stress of slab piers between tower columns under different construction methods and temperature conditions. [Findings] The stress of the slab pier area mainly depends on the load that it continues to bear after casting. The moving load mainly produces the bending moment, axial force, and torque of longitudinal direction in the lower tower column. Moreover, the direction of the longitudinal bending moment is opposite to that of produced by the dead load, which is beneficial to the stress of the slab pier structure. The transverse prestress of the post‐cast strip can exert transverse pressure on the slab pier area, and there is stress concentration at the construction boundary. Under the condition of overall temperature rise and decrease of the lower tower column, there are tensile stresses at the connection between the plate pier rib and the base,and the connection between the plate pier and the lower tower column. [Conclusions] The stress of the structure is safe when the post‐cast strip is set in the slab pier area of the lower tower column. Considering a solar temperature rise of 5~30 ℃ at one side of the slab pier area of the lower tower column, the tensile stress value of the lower tower column is lower than the concrete standard strength value of 2.74 MPa. Hence, the concrete cracking of the lower tower column is not caused.
