刚构—斜拉组合桥是一种新型组合结构,计算与分析参考资料相对较少。本文以某桥为例,给出了主桥结构计算与分析的成果,通过索力优化,得到了受力较优的成桥状态。研究成果对同类大桥的设计与计算工作具有一定的理论指导作用。
Rigid-tensioned composite bridge is a new type of composite structure with relatively few calculation and analysis references. Taking a certain bridge as an example, this paper gives the results of the calculation and analysis of the main bridge structure. Through the optimization of the cable force, the bridge state with superior stress is obtained. The research results have certain theoretical guidance on the design and calculation of similar bridges.
