以之江大桥拱形钢塔斜拉桥为背景,通过空间有限元分析对索塔锚固区在运营阶段最大索力作用下的受力性能进行了研究。结果表明:锚箱在运营阶段索力最大的荷载组合工况,最大Von Mises应力不超过150MPa,结构具有足够的安全储备。
Taking the arch bridge of arch bridge of Zhijiang Bridge as the background, the force performance of the anchorage zone of pylon under maximum cable force during operation stage was studied by means of space finite element analysis. The results show that the maximum Von Mises stress of the anchor box does not exceed 150MPa and the structure has sufficient safety reserve during the operation phase.
