摘要
斜拉桥斜缆索的水平分力对主梁产生轴向压力，这种作用力可以增强预应力混凝土主梁的抗裂性，同时也增加了钢梁的局部失稳危险性。要保证拉索与主梁连接的强度、刚度和可靠性，保证局部稳定性，应将集中承担的力合理地分散到全截面。本文就广东省汕头市宕石大桥钢箱梁索梁锚固区的传力路径和应力应变状态，进行了结构试验和理论分析。
The level forces of inclined cables in cable stayed bridge produce axis pressure on main beam. The action can raise the anti crack capacity of prestress concrete beam,but may cut down the local steadiness of steel beam. It is necessary to make sure of strenth, rigidity, reliability and local steadiness of main beam. The force on beam must be transmitted to the whole sections of the beam. In this paper, the structure tests of the Que Shi Bridge have been carried out, and the stress strain states and the ways of transmitting force in the anchorage between box shaped steel beams and cables have been studied.
