摘要
以三县洲斜拉桥为工程背景， 运用现代有限元分析方法， 对墩、塔、梁固结节点进行了空间应力分析，
The pier - tower - beam joint used as a structural componentin a cable - stayed bridge sys tem is one ofthe most important key component The behavior ofthe joint under load and the construc tion of the joint are complicated Based on a practical project ,the spatial stress distribution ofthe jointunder dead load and live loads is analysed in detail by modern finite element method and optical- elas tic test The result can be used as a reference for the design and construction ofthis structural system
