下风侧

列车在下风侧时的桁梁三分力系数较列车在上风侧时大；列车在桥上运行时，会增大桁梁的升力系数和力矩系数，降低桁梁的阻力系数。

The three aerostatic coefficients are larger when the train is on leeward side of deck than on windward side of deck , the lift coefficients and pitch coefficients of girder are raised when train passing though the bridge but the drag coefficients are reduced .
