摘要:
采用风洞试验的方法研究了4种不同表面的斜拉索(包括1种光索、2种螺旋线索和1种凹坑索)在不同倾角下的顺桥向阻力系数.试验结果表明:凹坑索和2mm螺旋线索的阻力系数相差不大,均可应用于斜拉桥的设计当中.根据试验结果给出了形式上比较简单的用于计算斜拉索不同倾角下阻力系数值的拟合公式.分析表明,此拟合公式和试验结果拟合较好且偏于安全.
Abstract:
The wind tunnel test method was used to study the resistance coefficient of the bridge at different inclination angles of four different surfaces (including one light cable, two spiral cues and one pit cable) at different inclination angles. The test results show that the resistance coefficients of pit cable and 4mm spiral clue are not much different, and they can be applied to the design of cable-stayed bridge. According to the experimental results, a relatively simple fitting formula for calculating the resistance coefficient value of the cable-stayed cable at different inclination angles is given. The analysis shows that this fitting formula and the experimental results fit well and are safe.
