Taking the Second Wuhu Yangtze River Highway Bridge as an example,the design of the bridge tower is introduced in de-tail.Aiming at the modeling of the split column bridge tower of the bridge,the analysis was carried out by using finite element software.The stress performance of tower column,tooth plate anchorage cable segment,cable tower limb segment,middle cross beam segment and base plate segment are analyzed in detail.The calculation results show that the stress level of the bridge tower column meets stand-ard requirements,the safety reserve of the structure is good,and the section size of the split column bridge tower is reasonable.Howev-er,under the most unfavorable load conditions,the bottom surface of the tower limb,the beam between the two tower limbs and the top surface of the base plate will produce large tensile stress,and certain strengthening measures need to be taken.It can be considered to increase the transverse prestressed steel wires,which has obvious effect on the improvement of local tensile stress.Finally,reasonable suggestions are put forward for the design of similar bridge towers.
