Through the section model wind tunnel test, this Paper studies the influence of vibration dampingmeasure to the three-component force coefficient of the structure , in order to improve structural characteristics.The research based on the guide plate position, the central trough opening rate, baluster drafty rate, repair cartrack position , windbreak , vehicle as the influencing factors of three-component force coeficient. The resulteshow that the changes of the three-component force coeficients directly affect the static wind loads, and the in.fluence of changes of these parameters to the static wind load can not be ignored. The most obvious influencepavement to drag coeficient is windbreak, in the large attack angle, the resistanee coefficient rose of comple-ted status with windbreak.
