A practical method of identifying the locations of the damages in stay cables is proposed by combination usage of the frequency change of vertical bending vibration mode, the modal curvature change of the main girder and the change of stay cable force of the cable-stayed bridges. 提出了综合运用斜拉桥竖弯振型频率变化、主梁模态曲率变化以及拉索索力变化进行拉索损伤位置识别的实用方法。

Generally speaking, the construction environment of bay bridges is harsh, especially in the large wind speed and unsteady wind regime, which brings unfavorable influence to the construction of steel box girder and stay cables of the Long-span Cable-stayed Bridge. 跨海湾大桥一般施工环境比较恶劣,尤其是风速比较大,且风况极不稳定,对大跨度斜拉桥的施工带来了很不利的影响。
The research results about the curved girder bridge diseases are very rich. But they still stay on static analysis. 有关曲线梁桥的病害研究成果已经十分丰富了,但一般主要对病害的静力分析方面。
