【摘要】 随着信息化与交通建设的深度融合，桥梁数字化建造的应用领域及深度不断增加。以大跨度曲线斜拉桥为代表的复杂桥型结构，因其体量庞大、异型结构多以及空间线形多变等特点，制约了BIM技术在大跨度复杂桥梁中的应用。鉴于此，本文结合国内曲率半径最小的空间异形曲线特大型斜拉桥的工程背景，引入Dynamo可视化编程技术，研发了小箱梁参数自适应的模型创建及自动化布设系统，提出了斜拉索建模-布设一体化的端点控制法，实现了大跨度曲线斜拉桥复杂构件数据驱动式离散型精准点控的自动化布设全过程编程应用。研究结果表明：该方法显著提升了大跨度曲线斜拉桥参数化建模的精细度、精准度和效率，与传统方法相比，有效控制箱梁中心线误差至2mm以内，坡度计算精度提高到0.1%，建模效率提升了76%，为BIM技术在大跨度复杂桥梁参数化智能建模中的应用提供参考。更多还原

【Abstract】 With the deep integration of information technology and transportation infrastructure development, the application field and digital construction for bridges are continually expanding. The complex bridge structures represented by the large-span curved cable-stayed bridges have the characteristics of massive scale, varying atypical structures, and complex spatial geometries, which have constrained the application of BIM technology in large-span complex bridges. For the extra-large cable-stayed bridge of space irregular curve, which has the smallest radius of curvature in China, the Dynamo visualization programming techniques are introduced to study the model creation and automated layout system for adapts parameters of small box girders. And an integrated end-point control method for cable-stay modeling and layout is proposed. This method enabled the automated layout of data-driven discrete precision point control for the complex components of large-span curved cable-stayed bridges. The results show that this method significantly enhances the precision, accuracy, and efficiency of parametric modeling for large-span curved cable-stayed bridges. Compared with traditional methods, the centerline error of the box girder is effectively controlled within 2 mm, the slope calculation accuracy is improved to 0.1%, and the modeling efficiency is increased by 76%. This provides a reference for the application of BIM technology in parametric intelligent modeling of long-span complex bridges.更多还原
