非对称钢拱塔斜拉桥 BIM 正向设计的应用

Application of BIM Forward Design for Asymmetrical Steel Arch Pylon Cable-stayed Bridge

摘要:

BIM技术不仅为桥梁设计提供了新的思路，还有效提升了桥梁设计品质。结合复杂航道钢桥的设计流程，基于CATIA“骨架+模板”的思路，针对主梁、塔柱、拉索和锚箱等全要素构件进行三维正向设计，开展了结构分析、二维出图和工程量统计等工作，验证了BIM技术在复杂航道钢桥设计中的工程适用性，为BIM技术在同类桥梁设计中的应用提供了参考。

Abstract:

BIM technology not only provides new ideas for bridge design, but also effectively improves the quality of bridge design. Combined with the design process of steel bridge in complex waterway, the three-dimensional forward design is carried out for total-element components of main beams, pylon columns, cables and anchor boxes according to the idea of CATIA "skeleton + template". The structural analysis, two-dimensional drawing and engineering amount statistics are carried out, and the engineering applicability of BIM technology in the design of complex waterway steel bridges are verified, which provide the reference for the application of BIM technology in the design of similar bridges.
