Utility tunnel layout method based on three-dimensional virtual city

Abstract

The invention relates to a utility tunnel layout method based on a three-dimensional virtual city, which comprises the steps of preprocessing remote sensing image data, digital elevation model data and three-dimensional building model data and establishing a three-dimensional virtual city system; in the three-dimensional virtual city system, realizing the generation and management of an underground three-dimensional pipe network model based on pipe point data, pipe well data and two-dimensional pipeline data; according to the underground three-dimensional pipe network model, selecting the starting point and the end point of a needed pipe network and generating various pipe network layout scheme; according to relevant specifications and standards, conducting collision processing to the pipe network layout scheme, searching for pipe network surrounding facilities and analyzing pipe network layout influence factors; and conducting optimization analysis according to the pipe network layout influence factors, obtaining an optimized scheme suitable for the underground pipe network layout and administratively demonstrating a result in the three-dimensional virtual city system. By building the three-dimensional virtual city, building a dynamic model and generating and optimizing various pipe network layout schemes, the goal that the pipe network layout has a basis is realized and a support is provided for planning the underground sources and pipelines of cities.

Description

technical field [0001] The invention relates to a common ditch layout method, in particular to a common ditch layout method based on a three-dimensional virtual city. Background technique [0002] Urban common ditch is responsible for the tasks of information transmission, energy transmission, water supply and drainage, etc., and is the foundation of urban development, so it is known as the lifeline of the city. However, with the rapid development of the city, the material flow and energy flow in the city are gradually increasing, which makes the spatial distribution of urban underground pipelines more and more narrow. To explore the optimization method of underground three-dimensional pipeline network layout will provide a basis for urban underground resource management, pipeline planning and urban planning. Construction provides auxiliary decision-making, which is of great significance. [0003] Therefore, how to achieve better management of the layout of underground spac...

Problems solved by technology

[0004] The traditional underground professional pipeline network adopts manual methods, the management efficiency is low, it is difficult to dynamically manage the common trench, and it is easy to cause pipeline accidents in a narrow space

In addition, the traditional common trench management is based on two-dimensional basis, which cannot visually display the distribution of pipelines and the mutual position of pipe sections
