Realistic 3D China,as a novel means and method for comprehensive analysis,multi-dimensional display,and trend analysis of economic and social factors under modern technological conditions,is playing a greater role in accelerating the construction of an economic layout and national spatial system that reflects the requirements of high-quality development,especially in the development of new productive forces.The 3D spatial information of urban underground pipelines is a component of the construction of realistic 3D China.This article combines multi-source data fusion technology based on spatial analysis,integrated spatio-temporal data collaborative collection technology of above ground and underground,and component level pipeline model construction technology based on BIM to comprehensively consider the technical means of 3D construction of underground pipelines.It has certain reference and application value for supporting and empowering the construction and development of 3D scenes for the digital transformation of super large cities.
