摘要
斜拉索经过长期的运营以后,桥梁状况已经发生了比较大的变化,在斜拉桥换索过程中,单纯根据理想状态进行换索过程的仿真分析,是不能够达到安全性预测目的的。采用交通荷载状态控制法对斜拉桥的换索过程进行安全性预测理论简单,且安全实用,减少了换索过程的盲目性,可确保换索工程的顺利进行。
Through a long period of operation of stay cable, the state of bridges has changed greatly. In the process of cable replacement for cable-stayed bridges, the simulation analysis of cable replacement process based on ideal state cannot achieve the purpose of security forecast. Adopting traffic load state control method to carry through security forecast of the cable replacement process for cable-stayed bridges is not only simple in theory, but also safe and practical, which can reduce the blindness of cable replacement and insure that the cable replacement engineering go forward well.
