摘要
该文介绍了对正在施工中的杭州市文晖大桥进行斜拉索的索力调整的优化计算。通过结构的敏感度分析和模型修正使计算模型向当前实际结构逼近,在此基础上以主梁内力和线形为主要控制目标对索力调整值进行优化,可为后期施工的索力调整过程提供更加真实可靠的理论依据。
Optimum calculations are made on cable force adjustment for the under-construction Hangzhou Wenhui bridge. Based on structural sensitivity analysis and model amendment, the calculation models are more approached to the actual structure, and then the cable force adjusting values are optimized with the internal force and alignment of girders as the main control objectives to provide more reliable theoretic basis for cable force adjustment in construction afterwards.
