  • Based on the 2D fluid-structure coupling theory, the wind-induced vibration responses of transmission lines across 2 close hills were calculated. Both the load on the wire by the mountain wind and the surface wind pressure change caused by wire vibration with its influence on the flow field were considered. Firstly, the correctness of the method was verified in comparison with the existing literature results. Then, the numerical wind tunnel model for the transmission line across 2 close hills was established. The average wind speed characteristics of the canyon and mountain pass topography as well as the distribution characteristics of the corresponding wind pressure were analyzed. The distributions of aerodynamic coefficients and vertical displacements were analyzed. The numerical results show that, in the transient wind field, the acceleration effect of the mountain pass is more significant than that of the canyon, and the acceleration ratio at the middle of the line is more important. The distribution of wind pressure around the wire is also inconsistent due to the influence of different topographic wind fields. Under the canyon topography, the distribution of wind pressure around the wire is stable with time. Under the mountain pass topography, the wind pressure around the wire fluctuates with time. The smaller the distance between the 2 hills is, the greater the variation range of the resistance coefficient time history curve will be, so is the change of wind pressure. The updraft under the mountain pass topography makes the wire subject to greater lifting force and vertical wind deviation.
