摘要: 利用BIM技术以及参数化设计方法对复杂景观桥梁设计展开研究，基于Rhinoceros软件建立全桥参数化BIM模型，研究了BIM技术在桥梁方案设计，结构优化，设计合理性检查，工程量统计以及辅助出图等方面的应用。同时实现BIM模型与实体有限元软件之间的数据对接，着重分析异形索塔的力学特性。研究表明：BIM技术与参数化设计作为桥梁三维正向设计的基础，在工程设计阶段可有效控制设计误差，提高设计效率及质量。异形索塔力学分析表明：索塔整体受力以受压为主，锚固区由于环向预应力的施加，具有较高的压应力安全储备,各向应力水平均在可控范围之内。为BIM技术在桥梁工程设计阶段的应用提供了一个有效的技术路线。

Abstract：The BIM technology and parameterized design method were used to study the complex landscape bridge design. Based on Rhinoceros software, the full bridge parameterized BIM model was established. The application of BIM technology in bridge scheme design, structure optimization, design rationality check, engineering quantity statistics and auxiliary design drawing was studied. At the same time, the data docking between the BIM model and the finite element software was realized. And the mechanical properties of the special-shaped cable tower were analyzed emphatically. The research shows that BIM technology and parameterized design are the basis of three-dimensional forward design of bridge, which can effectively control design errors and improve design efficiency and quality in engineering design stage. The mechanical analysis of the special-shaped cable tower shows that the overall stress of the cable tower is mainly under pressure, and the anchorage zone has a relatively higher safety reserve of compressive stress due to the application of circumferential prestress. The stress levels in all directions are within the controllable range. It provides an effective technical route for the application of BIM technology in the design stage of bridge engineering.

Key words ： bridge engineering, landscape bridge, BIM technology, parameterized design, special-shaped cable tower, mechanical performance
