地锚式悬索桥加固拓宽方案比选实例

An Example of Comparison and Selection of Proposals for Reinforcing and Widening Ground-anchored Suspension Bridges

以某工程为例,介绍了地锚式悬索桥加固拓宽改造方案的比选思路及过程。具体阐述了采用有限元理论计算分析得到的拟订改造方案的依据;提出斜拉悬吊组合体系是此类工程的一种可行的解决方案,为工程实践提供设计思路。

Taking a project for example, introduction is made to the concept and process of comparing and determine the proposal for reinforcing and widening a ground-anchored suspension bridge, with detailed description of the basis for the reconstruction proposal obtained through calculation and analysis with the theory of finite elements, indicating the cable stay and suspension combination system is applicable for that type of works, a new design concept in engineering practice.
