摘　　要：斜拉索的拉索锚固是将一个拉索的局部集中力安全、均匀地传递到塔柱的重要受力构造,本文通过龙江路大桥索塔锚固区的设计,介绍了预应力粗钢筋在斜拉索锚固中的应用。结果表明,采用预应力粗钢筋作为斜拉索锚固的方式具有锚固可靠、操作简便、耐久性好的特点。Stayed cable anchorage is an important structure that transfers concentrated force from stayed cable to pylon safely and equably.In this paper, the application of prestressed reinforcing rebar in stayed cable anchorage is introduced based on the design of pylon anchorage zone of Longjianglu bridge.The results show that using prestressed reinforcing rebar in stayed cable anchorage is reliable, simple and durable.
