| 摘 要： | 针对复杂拉索景观斜拉桥调索困难的难题，以某座空间扭曲桥塔斜拉桥为例，提出一种实用的索力优化方法。该方法可实现直观、可调的多目标索力优化，不受程序限制，快速进行合理索力的确定；亦可实现设计人员的主观可控性，帮助设计人员在调索的同时，快速掌握结构的关联特性。

| Abstract: | In view of the difficult problems of complex cable adjustment in landscape cable-stayed bridge, taking a spatial twisted pylon cable-stayed bridge as an example, a practical method of cable force optimization is proposed. The method can realize the intuitive and adjustable multi-objective cable force optimization, which is not limited by the program and can quickly determine the reasonable cable force. The method can also realize the subjective controllability of the designers, and help the designers quickly grasp the structure association characteristics while adjusting the cables. |
