【摘要】：燃气建设是城市建设的重要组成部分,随着城市的发展,燃气设施的建设也不断进行,在地上、地下形成了大规模错综复杂的城市燃气管网系统。城市燃气管网事故的频繁发生,造成了严重的人员伤亡和财产损失。为有效遏制城市燃气管网事故造成严重损失,就必须加强城市燃气管网应急救援系统方面的研究。首先,论文对燃气性质,燃气管网结构以及燃气管道事故的特点,包括燃气事故的的成因、发生、发展机理及其可能导致的二次事故等进行分析,根据事故应急救援组织结构和职责,提出了城市燃气管网事故应急救援的应急救援程序流程,确定了城市燃气管网应急响应辅助救援系统的功能需求和系统数据库的总体结构设计和内容设计。然后针对二维管网系统空间层次感差的缺点,通过SketchUp三维建模技术,在ArcGIS平台实现了燃气管网场景的三维建模。然后运用二三维联动的技术,结合ArcGIS Engine组件进行二次开发,实现了系统的二维三维的交互功能,将二维地图与三维场景的优缺点进行互补,增强系统的实用性。其次考虑到事故后果模型在应急救援上的应用,本文详细研究了城市燃气事故的各类事故模型,确定了燃气事故泄漏、扩散、火灾和爆炸的数学模型。最后根据系统的功能需求对城市燃气管网应急响应辅助救援系统的总体框架进行设计,完成了事故后果分析模块、管网抢救分析模块,应急救援指挥决策模块等功能模块,实现应急救援的快速准确反应,提高对燃气事故的应急处置能力,减少事故所带来的损失。
[Abstract]:Gas construction is an important part of urban construction, with the development of the city, the construction of gas facilities is also ongoing, on the ground. A large scale and complicated urban gas pipeline network system has been formed underground. The accidents of urban gas pipeline network occur frequently. In order to effectively curb the serious losses caused by urban gas pipeline accidents, it is necessary to strengthen the research on the emergency rescue system of urban gas network. First, this paper focuses on the nature of gas. The structure of gas pipeline network and the characteristics of gas pipeline accidents, including the causes of gas accidents, occurrence, development mechanism and possible secondary accidents are analyzed, according to the accident emergency rescue organization structure and responsibility. The procedure flow of emergency rescue for urban gas pipe network accident is put forward. The functional requirements of the auxiliary rescue system for the emergency response of the urban gas network and the overall structure design and content design of the system database are determined. Then the shortcomings of the spatial hierarchy of the two-dimensional pipeline network system are pointed out. Through SketchUp 3D modeling technology, the 3D modeling of gas pipe network scene is realized on the ArcGIS platform, and then the technology of two and three dimensional linkage is used. Combined with the secondary development of ArcGIS Engine component, the interactive function of 2D and 3D is realized, and the advantages and disadvantages of 2D map and 3D scene are complementary. Secondly, considering the application of accident consequence model in emergency rescue, this paper studies all kinds of accident models of urban gas accident in detail, and determines the leakage and diffusion of gas accident. Finally, according to the functional requirements of the system, the overall framework of the auxiliary rescue system for emergency response of urban gas pipeline network is designed, and the accident consequence analysis module and the rescue analysis module of the pipeline network are completed. The function modules such as emergency rescue command and decision module can realize the rapid and accurate response of emergency rescue, improve the ability to deal with gas accidents, and reduce the losses caused by accidents.
