摘要:
鉴于高速铁路对桥梁的受力状态、线型、刚度等要求非常高，本文对下承式拱桥在成桥状态下吊索合理内力的确定和施工阶段张拉控制力的计算进行了分析研究，并以国内某高速铁路系杆拱桥的设计、施工过程为例，重点介绍了刚性吊杆法、影响矩阵法的计算原理及过程，并将影响矩阵法的计算结果与正装法、倒装法、无应力状态法进行了对比，可为类似桥梁的设计、施工提供借鉴。
Abstract:
In view of the high demand of the high speed railway for the bridge's stress state, Linetype and stiffness, the determination of the reasonable internal force of the sling cable and the calculation of the tension control during the construction stage are analyzed and studied in this paper. Taking the design and construction process of a high-speed railway arch bridge as an example, the calculation principle and process of the rigid suspension rod method and the influence matrix method are mainly introduced, and the calculation results of the influence matrix method are compared with the formal method, the reverse method, and the stress-free state method, which can provide reference for the design and construction of similar bridges.
