【摘要】：隨著我國城市化建設(shè)進(jìn)程的加速和城市范圍的不斷擴張,地下管線作為城市重要的配套基礎(chǔ)設(shè)施,其建設(shè)發(fā)展也非常迅速,各類地下管網(wǎng)縱橫交錯,貫穿于城市的每個角落。但隨著地下管線建設(shè)數(shù)量的增加,城市地下管線安全事故也越來越多。城市地下管線安全隱患已經(jīng)成為我國城市發(fā)展的重大威脅,從近年來發(fā)生的多起典型地下管線事故來看,對于地下管線這樣一個縱橫交錯、分布范圍廣、公共性強、易損性高、各類管線高度關(guān)聯(lián)的系統(tǒng),地下管線空間布局存在的問題是城市地下管線安全隱患的重要來源之一。地下管線空間布局安全性與城市的安全密切相關(guān),一方面,城市的發(fā)展必將推動城市配套基礎(chǔ)設(shè)施的建設(shè),地下管線的規(guī)模隨之?dāng)U大,管線空間布局也將不斷變化;另一方面,地下管線的建設(shè)發(fā)展將對城市擴張帶來影響,此后的城市建設(shè)和地下空間資源開發(fā)必然受已有地下管線空間布局的約束。因此,地下管線空間布局安全性的研究,可為規(guī)劃部門提供科學(xué)、量化、空間化的地下管線空間布局安全隱患信息;為城市地下管網(wǎng)規(guī)劃、建設(shè)、運營、維護(hù),地下綜合管廊建設(shè)等提供科學(xué)依據(jù);對保障人民生命財產(chǎn)安全和城市可持續(xù)發(fā)展具有重要的科學(xué)意義和實際價值。本研究依據(jù)地下管線空間布局特點和布局原則,確定對地下管線安全有較高影響的評價指標(biāo),并進(jìn)一步利用層次分析法確定各評價指標(biāo)的權(quán)重,確立了地下管線空間布局安全性評價體系,構(gòu)建了地下管線空間布局安全性單指標(biāo)評價模型與綜合評價模型,建立了安全性分析技術(shù)流程,最終實現(xiàn)了基于GIS的城市地下管線空間布局安全性評價。最后,結(jié)合工程實例,實現(xiàn)了 W城市某區(qū)域的地下管線空間布局安全性分析,取得了良好的評價效果,驗證了本研究評價理論、方法的可靠性。論文主要包括以下幾個部分:(1)調(diào)研國內(nèi)外關(guān)于管道安全性評價相關(guān)的文獻(xiàn)、資料。分析現(xiàn)階段已取得的研究成果以及發(fā)展方向,發(fā)現(xiàn)現(xiàn)有研究的不完善,提出本文基于GIS的城市地下管線空間布局安全性的研究理論及研究方法。(2)在充分掌握地下管線空間布局特點的基礎(chǔ)上,依據(jù)地下管線空間布局的原則和要求,結(jié)合現(xiàn)有資料,提出地下管線占壓、凈距、敷設(shè)順序、埋設(shè)深度等4個評價指標(biāo),運用層次分析法確定各指標(biāo)對空間布局安全性影響程度的權(quán)重。(3)根據(jù)各指標(biāo)的不同,基于GIS分析方法,分別構(gòu)建相應(yīng)的分析模型以及探索相應(yīng)分析的實現(xiàn)流程。在單指標(biāo)分析模型的基礎(chǔ)上,構(gòu)建多指標(biāo)綜合評價模型。(4)利用本研究提出的基于GIS的地下管線空間布局安全性評價方法,結(jié)合W市地下管線具體情況,實現(xiàn)對該市某區(qū)域地下管線占壓、凈距、順序、埋深等隱患以及空間布局安全性總體情況分析,將分析結(jié)果輸出并可視化表達(dá),分析結(jié)果提交相應(yīng)城市規(guī)劃部門,經(jīng)核實符合研究區(qū)建設(shè)發(fā)展實際情況。
[Abstract]:With the acceleration of urbanization and the continuous expansion of urban scope, underground pipelines, as an important supporting infrastructure of the city, are also developing very rapidly, and all kinds of underground pipe networks are crisscrossed. It runs through every corner of the city. However, with the increase of the number of underground pipeline construction, there are more and more underground pipeline safety accidents. The hidden danger of urban underground pipeline safety has become a major threat to urban development in China. In view of the many typical underground pipeline accidents in recent years, for the underground pipeline such a system with crisscross, wide distribution, strong publicity, high vulnerability and high correlation of all kinds of pipelines, The problems existing in the spatial layout of underground pipelines are one of the important sources of hidden dangers of urban underground pipeline safety. The safety of underground pipeline spatial layout is closely related to the safety of the city, on the one hand, The development of the city will promote the construction of the supporting infrastructure of the city, the scale of the underground pipeline will expand with it, and the spatial layout of the pipeline will change constantly. On the other hand, the construction and development of the underground pipeline will have an impact on the expansion of the city. Since then, urban construction and exploitation of underground space resources are bound to be restricted by the spatial layout of existing underground pipelines. Therefore, the research on the safety of underground pipeline spatial layout can provide scientific and quantitative information for planning departments. The spatial distribution of underground pipelines provides scientific basis for the planning, construction, operation, maintenance and construction of underground pipelines. It is of great scientific significance and practical value to ensure the safety of people's life and property and the sustainable development of the city. According to the spatial layout characteristics and layout principles of underground pipelines, this study determines the evaluation indexes that have a higher impact on the safety of underground pipelines. Furthermore, the weight of each evaluation index is determined by analytic hierarchy process (AHP), the safety evaluation system of underground pipeline spatial layout is established, and the single index evaluation model and comprehensive evaluation model of underground pipeline spatial layout safety are constructed. Finally, the safety evaluation of urban underground pipeline spatial layout based on GIS is realized. Finally, the security analysis of underground pipeline spatial layout in a certain area of W city is realized by combining with an engineering example. Good evaluation results have been obtained, and the reliability of the evaluation theory and method has been verified. The paper mainly includes the following parts: 1) the literature on pipeline safety evaluation is investigated at home and abroad. Data. Analysis of the current research achievements and development direction, found that the existing research is not perfect, This paper puts forward the research theory and research method of urban underground pipeline spatial layout security based on GIS. On the basis of fully mastering the characteristics of underground pipeline spatial layout, according to the principles and requirements of underground pipeline spatial layout, combined with the existing data. The paper puts forward four evaluation indexes of underground pipeline, such as occupation pressure, net distance, laying sequence and laying depth, and uses AHP to determine the weight of each index to the safety degree of spatial layout. (3) according to the difference of each index, it is based on GIS analysis method. Build the corresponding analysis model and explore the corresponding analysis process. On the basis of the single index analysis model, Constructing multi-index comprehensive evaluation model. (4) using the safety evaluation method of underground pipeline layout based on GIS proposed in this study, combining with the concrete situation of underground pipeline in W city, the paper realizes the proportion of pressure, net distance and sequence of underground pipeline in a certain area of this city. The hidden danger of buried depth and the general situation of spatial layout security are analyzed. The analysis results are output and visualized, and the results are submitted to the corresponding urban planning departments, which are in accordance with the actual situation of the construction and development of the study area.
