温州大门大桥仿真与自适应控制分析

摘要

大跨度PC斜拉桥是设计、监控、施工高度耦合的结构,而施工控制的效果是PC斜拉桥施工质量的重要指标之一.以温州大门大桥为例, 结合该桥的施工工艺和方案,对PC斜拉桥施工自适应控制系统原理进行了介绍,并对全桥施工进行了仿真计算分析,同时对成桥状态进行了参数比较分析.%Large span PC cable-stayed bridge was a structure with the design, monitoring and construcfion highly coupled, and the effect of construction control was one of the important indicators of the quality of construction. This paper takes Wenzhou Gate Bridge as an example. After considering the specific construction craft , a suitable adaptive control for PC cable-stayed bridge was built up and introduced. The simulation analysis was carried through, and then the parametric analysis was conducted as well
