| The comprehensive pipe gallery is an important carrier for improving the city’s carrying capacity and intensive use of land resources and underground space.The construction and operation of the integrated pipeline gallery will completely change the messy situation of the individual construction and management of each pipeline in the past,effectively alleviate the problems of "road zippers" and "air spider webs",and at the same time improve pipeline safety and disaster prevention capabilities.As a typical mountain city,Chongqing has the characteristics of more mountains in the planned area,large terrain undulations,more roads crossing mountains,and complicated pipeline laying.Based on Chongqing’s complex topography and landforms and many influencing factors,this paper uses GIS spatial analysis as a method to evaluate the pipelines of a comprehensive pipeline gallery in Chongqing.The GIS spatial analysis method can combine and superimpose many influencing factors,and intuitively reflect them through graphics,and at the same time quantify the evaluation system of the suitability of the comprehensive pipeline corridor construction.Through the construction of the quantitative evaluation system,this paper rationally plans the layout of the comprehensive pipe gallery,and provides a more scientific method for constructing the comprehensive pipe gallery layout system.The main content of this article is divided into four parts: introduction,basic theoretical research,case analysis and research,and a total of five chapters.The first chapter is the introduction,the main content is to introduce the research background of the subject,the current research status at home and abroad,the research object and content,the research purpose and significance,and the introduction of the research method and framework of the subject.The second chapter is the basic theoretical research part.Through the analysis of the relevant literature on the planning and design of the comprehensive pipeline corridor in the mountainous city,it summarizes the methods and content adopted by the current comprehensive pipeline corridor planning and design in Chongqing.Chapters 3 and 4 are specific analysis and research parts.Chapter 3 mainly analyzes how to apply the GIS spatial analysis method to the integrated pipeline gallery.The fourth chapter mainly applies the analysis results to the planning and design of an underground comprehensive pipe gallery in Chongqing,and verifies the application effect of the GIS spatial analysis method through actual cases.The fifth chapter is the conclusion part.It is necessary to summarize the application of GIS spatial analysis method in the planning and design of comprehensive pipeline corridors,and establish a set of comprehensive pipeline corridor layout and corridor pipeline selection evaluation index system in mountainous cities,which can be used for other mountainous cities to integrate Provide experience in pipe gallery planning and design. |
