Abstract
The thesis studies the types and characteristics of underground pipelines,analyzes the application advantages of 3D modeling and visualization technology in the operation and maintenance management of underground pipelines,and expounds the data organization method,structured expression of underground pipe sections,underground pipe points and underground pipeline networks,as well as the calculation methods of basic data and key coordinate points.It studies the 3D modeling process of straight pipes,bent pipes,different articulation types and the visualization technology of pipeline pipe points.The visualization technology effectively overcomes the disadvantages of the two-dimensional underground pipeline management mode,such as unclear pipeline display,unintuitive,poor readability and poor practicality,and effectively improves the utility and value of the three-dimensional model of the underground pipeline in the actual operation and maintenance.
