泾河特大桥所在地区的短时阵风较大,结合泾河桥的实际施工情况,重点对其6号桥墩和7号桥墩最大悬臂状态时的稳定性进行了分析。结果表明,风荷载对该桥最大悬臂状态时的稳定影响有限,各荷载工况下,6号和7号墩的稳定系数均大于10,具有足够的稳定安全储备。
The short-time gusts in the area where the Jinghe River Bridge is located are large. Based on the actual construction of the Jinghe River Bridge, the stability of the maximum cantilever state of the No.6 pier and No.7 pier is analyzed. The results show that the wind load has a limited influence on the stability of the bridge under the maximum cantilever condition. Under the load conditions, the stability coefficients of Pier 6 and Pier 7 are both greater than 10, which has sufficient stable safety reserves.
