摘要
景观桥梁具有造型优美、线条独特、可重复性差等特点,传统二维设计难以满足设计生产的需求。BIM技术为设计提供了一个三维数字化平台,可直接用于复杂形体的创意表达和结构优化,其参数化设计手段将桥梁复杂形态通过关键参数控制,以骨架模型驱动桥梁族构件,有效地提高了景观桥梁的设计质量。为探究景观桥梁的BIM设计方法和应用思路,以合川渠江景观大桥为例,结合"R+GH+R"的BIM协同设计平台,建立全桥的整体信息模型,并进行施工全过程的模拟,为景观桥梁的BIM设计和应用实践积累经验。
Landscape Bridges have the characteristics of complex modeling,nonlinear change and substitutability.The traditional design method is difficult to meet the design and production requirements.BIM provides a three-dimensional digital platform for design.It can be directly used in creative expression and structural design optimization of complex shape.Parameterized design in BIM technology translates complex conditions into structural parameters.It is a good countermeasure to deal with complex component by controlling the structure of the structure through predetermined logic rules.The frame model can be used to drive family structures,which improves the design quality of landscape bridge effectively.This paper will take the HechuanQu River Landscape Bridge as an example.Combined with the"R+GH+R"BIM collaborative design platform.we can build the bridge information model and simulate the whole construction process.Accumulating experience for BIM design and application practice of the landscape bridge.
