Galloping phenomenon of large scale spire type main cable of suspension bridge during construction seriously affects the construction progress and construction personal safety. Base on the analysis of galloping and aerostatic coefficients of large scale spire type main cable of suspension bridge considering effect of construction catwalk during construction, the numerical simulation method of CFD is used. The design parameters of catwalk and the main cable of Xihoumen Suspension Bridge are adopted. Firstly, referring to the results of wind tunnel test for catwalk, validity of the settings method of parameters for numerical simulation is verified. Secondly, the drag and lift coefficients of triangles and pentagons shape main cable during construction are calculated, considering the aerodynamic interference effect of catwalk. Then, the galloping coefficients of main cable for different working conditions are calculated by the Deng-Hato criterion during construction. Results show: the numerical calculation parameter settings are correct; the drag coefficients of triangle shape and pentagon shape main cable for different working conditions do not change obviously during construction, with the increase of cable strand considering aerodynamic interference effect of catwalk, and the downward trend of lift coefficients is more and more obvious. Comparing the galloping coefficients of different working condition and with the number of strand in the same layer increasing, the galloping coefficients of different working condition declined gradually, which shows that galloping is more likely to happen during the symmetric shape working condition than the unsymmetrical shape working condition.
