摘　　要：随着近年来业主对桥梁的景观造型要求的提高,各种曲线造型的桥梁应运而生,这其中大部分是钢结构桥梁,具有空间曲线形状的结构用常规的二维图纸很难展现设计意图。设计本身虽只占用建筑全生命期的总成本的5%,但是却决定了其总成本的70%,如果设计中采用可视化程度高、数据信息高度整合、协调性好的BIM技术[1],可以完整展现设计院设计意图,提高钢板加工精度,改善施工组织,减少工程浪费,同时也为后期桥梁管养中BIM技术的实施提供准确可靠的模型载体。而目前复杂钢结构桥梁方向真正从设计开始的BIM技术应用尚属空白,解决后期BIM翻模不具备设计特性的问题,为真正做到从源头设计开始的全寿命周期BIM应用迈出关键的第一步。In recent years,with the owners of bridge landscape design requirements increasing,a variety of bridge curve shapes have emerged as the times require,most of which are steel structure bridges. It is quite difficult to show the design intention of 2D drawings with a conventional structure with space curve shape. Although design only takes up 70% of the total cost of the whole building life cycle,it decides 5% of its total cost. If uses the BIM technology with a high degree of visual data,high integration and good coordination in design stage,could completely show the intention of the design institutes,improve the machining precision of steel plate,improve the construction organization,reduce construction waste,but also provide accurate and reliable model for the implementation of BIM technology of a late bridge pipe carrier. At present,the complex steel structure bridge direction starts from real application of BIM technology design is still blank. BIM does not have the characteristics of mold design,is truly the first step the whole life cycle of BIM application from the beginning of design take the key.
