摘要
斜拉桥的施工是一项极其复杂的力学体系转换过程 ,必须进行施工监控。目前的施工监控是采用平面杆系的有限元法。针对仙桃汉江大桥 ,利用块体等空间单元 ,按照施工的真实步骤 ,逼真地建立了该斜拉桥一系列的空间计算模型。使得设计和监控更加逼近真实状态 。
The construction of cable stayed bridge is a very complex transforming course of structure system, construction control must be done. At present, the method of construction control is finite element analysis based on the plan member. In this paper, based on the Xiantao Hanjiang River Highway Bridge and used the space solid and link elements, a course of space calculating model of this bridge really true to life is set up, according to the real construction step. The design and control much close the real station, and the impetus to the construction of cable stayed bridge are given.
