天津永和斜拉大桥的桥塔顶部锚固区的光弹性试验,给出了在运营荷载作用下锚固区的应力分布情况,为设计提供了资料。试验结果表明,在锚具下局部应力影响范围不大;在锚具下锚板附近存在一个拉应力区。因此,必须采取有效的措施,以控制该区域过大的拉应力。 The photoelastic test of the anchorage zone of the bridge tower of Tianjin Yonghe Cable-Stayed Bridge and the stress distribution of the anchorage zone under the operation load are given, which provides the data for the design. The experimental results show that the influence of local stress is small under the anchorage. There is a tensile stress zone near the anchor under the anchorage. Therefore, effective measures must be taken to control the excessive tensile stress in the area.
