大跨连续刚构桥零号块施工托架设计

Bracket Design for Pier Table Construction of a Super-long Frame-Continuous Bridge

用大型有限元程序建立三维空间模型,分析了某高墩大跨连续刚构桥零号块施工时采用的三角形托架的受力状态,为托架的设计提供了重要的参考数据,同时介绍了采用三角形托架施工零号块过程中的注意事项,对同类桥梁的施工具有一定的指导意义。

The bracket for pier table construction of a Super-long Frame-Continuous Bridge is analyzed with the FEM program Ansys. A three dimensional finite element model is established. The result shows that the structure is safe. Also measures which shall be taken during construction are presented in details. It can be referenced to in the similar bridge construction.
