Using large eddy simulation method to analyze wind flow around trestle bridge deck,and with wavelet power spectrum analysis method,find that influence to the drag coefficient,the lift coefficient and the ten-sional moment coefficient will increase if wave amplitude increasing,and the last two coefficients will be influenced more acutely.
应用大涡模拟分析波浪对某型高架栈桥断面风载的影响,并结合小波功率谱分析,发现随着波浪振幅的增加,栈桥断面的三分力系数受到的影响加大,而且升力系数和扭矩系数比阻力系数对波浪振幅变化更加敏感;3个系数的振幅平均值都随波浪振幅增加而减小。
