摘　　要：针对混合梁斜拉桥合理成桥索力开展优化研究,结合改进的最小弯曲能量法对半漂浮体系单侧不对称混合梁斜拉桥合理成桥状态进行确定,通过模拟获得了在成桥状态时的索力值。最终得到的结果显示:实测结果与计算结果保持了较高的一致性,满足了规范的相关要求。本研究将为类似工程参数的设计与优化提供必要的基础数据。In this paper,the author carried out an optimization analysis of reasonable cable forces for hybrid beam cable-stayed bridges.By using the method of minimum bending energy,the author made an affirmation of the reasonable completion state of semi-floating system unilateral asymmetric hybrid beam cable-stayed bridge.The cable force value in the completed bridge state is obtained through simulation.The final study shows that the measurement results maintain a high consistency with the calculation results,which meets the requirements of the standards.This paper will provide some basic data for the design and optimization of engineering parameters.
