摘　　要：利用有限元程序ANSYS对某双幅桥面桥梁三分力系数进行了数值模拟研究。研究结果表明:双幅桥面阻力系数的气动干扰效应不容忽视,与单幅桥面主梁相比,下游桥面主梁阻力系数降低较多,上游桥面主梁阻力系数略有降低。上下游桥面的升力系数、升力矩系数的气动干扰效应不明显。Make use of finite element method procedure ANSYS to have carried out the numerical value simulation research on some double width bridge floor bridge three components moduli. The result studying is indicated： The double width bridge floor resistance modulus pneumatic disturbance effect does not admit ignoring, compared with cloth material of single width bridge floor main beam, Lower reaches bridge floor main beam resistance modulus lessening is more , the bridge floor main beam resistance modulus has lessening upstream a bit.The elevating force modulus fixing the lower reaches bridge floor,the litre of force moment modulus pneumatic disturbance effect are not obvious.
