摘　　要：空心板梁是主要的桥梁上部结构之一,广泛应用于城市桥梁中。它也是智慧城市建设中桥梁建模的主要对象。该研究基于ObjectArx二次开发平台,通过编写算法从桥梁图纸中自动识别出空心板梁各个组成部分的三维坐标,再将其输出至三维引擎,建立起空心板梁的高精度三维模型。该方法有效地提高了空心板梁建模的精准性与准确性,有较强的实用性。同时,也可广泛地运用到桥梁其他部件的建模工作中,具有一定的推广价值。Hollow slab beam is one of the main bridge superstructures,which is widely used in urban bridges.It is also the main object of bridge modeling in smart city construction.Firstly,based on the ObjectArx secondary development platform,the 3D coordinates of each component of the hollow slab beam can be automatically identified from the bridge architectural drawings by pro⁃gramming algorithms.Secondly,these coordinates sequence is exported to the 3D engine.Finally,the high-precision 3D model of the hollow slab beam is constructed by modeling program.This method effectively improves the precision and accuracy of hollow slab beam modeling and has strong practicability.At the same time,it can also be widely used in the modeling of other parts of the bridge and has some promotional value.
