摘　　要：以数据驱动的方式构建管道构件模型,需要将所有二维平面数据转换为三维可视化数据,建模时间较长。因此,提出面向地下管线普查测绘的管道构件BIM(建筑信息模型)参数化建模方法。首先,将地下管线管道的主体结构分解为多个构件,并将每个构件的截面数据作为参数化建模的基础。然后,运用BIM技术分析管道构件的参数化特征,构建包含几何参数、材料参数、位置参数等的BIM项目族库,结合现场采集的少量基础数据为各类型参数赋值。接着,从平行、相切等几何约束关系入手,定义建模约束条件。确定基础建模基准点后,导入BIM项目族库中的各项参数,得到管道构件三维可视化模型。实验结果表明,此方法整体建模时间较短,可以更好地辅助地下管线普查测绘工作。Constructing pipeline component models in a data-driven manner requires converting all 2D plane data into 3D visualization data,which takes a long modeling time.Therefore,a parameterized modeling method for BIM of pipeline components for underground pipeline general survey is proposed.Firstly,the main structure of underground pipelines is decomposed into multiple components,and the cross-sectional data of each component is used as the basis for parameterized modeling.Then,BIM technology is used to analyze the parameterized features of pipeline components,construct a BIM project family library that includes geometric,material,and positional parameters,etc,and assign values to various types of parameters based on a small amount of basic data collected on site.Next,starting from geometric constraint relationships such as parallelism and tangency,define modeling constraint conditions.After determining the baseline for basic modeling,import various parameters from the BIM project family library to obtain a 3D visualization model of pipeline components.The experimental results show that the proposed method has a shorter overall modeling time and can better assist in underground pipeline general survey work.
