摘要
体外预应力结构主要由体外索、转向块、锚固系统及防护系统等组成,其中体外索的配筋设计是关键。结合实践,介绍了体外预应力加固旧桥的原理及配筋计算方法。
The external prestressing structure consists mainly of external cable, redirector, anchorage system and safeguard system, among which the external cable focuses on the placing of reinforcement. Based on the practice, it presents the principles and calculadom of the external prestressing applied to strengthen the existing bridge.
