摘要
针对斜拉桥的结构特点和施工安装阶段主要面临的问题,以结构单元的无应力状态量作为控制主线,对成桥目标进行自动逼近,实现安装阶段多工序同步作业。模型试验和数座大跨度斜拉桥的施工实践证明了该方法的有效性和可靠性。
In the light of the structural features of cable\|stayed bridges and major problems commonly encountered in the erection stage of the bridges, the stressfree status amounts of structural element are used as principal path to automatically approximate the target values of the completed bridges, and to realize synchronous operations of multifarious construction procedures during the erection. The model tests and construction of several longspan cable stayed bridges prove that the method presented herewith is pretty effective and reliable.
