双拱的静力三分力系数、变异性以及受湍流度的影响等均与两拱间距宽度比及竖向相对位移有关。
Arch forces coefficients and fluctuating buffeting forces are mainly decided by the space width ratio and the relatively vertical displacement.
静力三分力系数用于描述风对桥梁的静力作用，气动导数是颤振和抖振分析方法的核心。
Static coefficients are defined to describe the static effect of wind on bridge, and the aerodynamic derivatives are used to describe the aerodynamic effect.
