【摘要】:云南省彝良至鎮(zhèn)雄公路(省道S302彝良至鎮(zhèn)雄段,以下簡稱彝鎮(zhèn)公路),是云南省昭通路網(wǎng)的重要組成部分,是滇東北地區(qū)發(fā)展的經(jīng)濟動脈。但由于復雜地質環(huán)境條件,公路沿線地質災害的頻發(fā),常常造成較大的經(jīng)濟損失與人員傷亡,不僅影響著道路沿線村鎮(zhèn)經(jīng)濟的發(fā)展,而且威脅著彝鎮(zhèn)公路沿線人民的生命安全。因此,對彝鎮(zhèn)公路沿線地質災害進行研究,得出其分布的一般規(guī)律,進而開展地質災害危險性評價是預防和管理公路沿線地質災害,確保彝鎮(zhèn)公路安全暢通的必要工作;而彝鎮(zhèn)公路地質災害危險性評價信息系統(tǒng)的設計與建立可以便捷的實現(xiàn)上述對公路沿線地質災害的管理與評價的需求。本文在分析和總結了國內外大量的地質災害危險性評價相關研究理論方法,以云南省彝鎮(zhèn)公路沿線公路有效影響范圍(500~1000m)為研究區(qū),在充分研究區(qū)內現(xiàn)狀地質災害(區(qū)內發(fā)現(xiàn)崩塌15處、滑坡28處、不穩(wěn)定斜坡93處)及成災地質規(guī)律的基礎上,通過對崩塌、滑坡以及不穩(wěn)定斜坡等數(shù)據(jù)的整理,在ARCGIS的技術支持下,對研究區(qū)地質災害危險性評價因子進行信息提取,并對各評價因子進行量化分級,結合層次分析法,計算出各個因子的權重,建立彝鎮(zhèn)公路地質災害危險性評價模型。在系統(tǒng)分析(包括用戶需求分析、數(shù)據(jù)分析及可行性分析)的基礎上,進行了彝鎮(zhèn)公路地質災害危險性評價信息系統(tǒng)總體設計和詳細設計,系統(tǒng)采用C/S模式,以ArcSDE Geodatabase和SQL Server技術設計建立了彝鎮(zhèn)公路沿線地質災害空間數(shù)據(jù)庫;最后選取ArcGIS Engine作為二次開發(fā)技術,利用面向對象的可視化編程語言C#在Visual Studio2010開發(fā)平臺上進行系統(tǒng)的開發(fā),構建集查詢檢索、統(tǒng)計分析、危險性評價、打印輸出以及數(shù)據(jù)動態(tài)維護等功能為一體的基于ArcGIS Engine的彝鎮(zhèn)公路地質災害危險性評價信息系統(tǒng)。該系統(tǒng)的建立,可為彝鎮(zhèn)公路沿線地區(qū)地質災害管理部門、路政管理部門等在防災減災以及保證道路安全方面提供技術支持,具有較大的應用價值。
[Abstract]:The Yiliang to Zhenxiong Highway in Yunnan Province (the section between Yiliang and Zhenxiong of Provincial Road S302, hereinafter referred to as Yi Town Highway) is an important part of the Zhaotong Road in Yunnan Province and the economic artery of the development of Northeast Yunnan.However, because of the complex geological environment conditions and the frequent occurrence of geological disasters along the highway, it often causes great economic losses and casualties, which not only affects the economic development of the villages and towns along the road, but also threatens the safety of the people's lives along the Yi-town highway.Therefore, it is necessary to study the geological hazards along the Yi-town highway and find out the general law of its distribution, and then to carry out the risk assessment of geological hazards to prevent and manage the geological hazards along the highway, and to ensure the safety and smooth running of the Yi-town highway.The design and establishment of risk assessment information system for highway geological hazards in Yi Town can meet the needs of the management and evaluation of geological hazards along the highway.This paper analyzes and summarizes a large number of relevant research theories and methods of geological hazard risk assessment at home and abroad, taking the effective influence range of highway along Yi town highway in Yunnan Province to be 500 ~ 1000m) as the research area.With the technical support of ARCGIS, the information of risk assessment factors of geological hazards in the study area is extracted, and the weight of each factor is calculated by combining the analytic hierarchy process (AHP) with the quantitative classification of each evaluation factor.The risk assessment model of highway geological hazard in Yi town is established.On the basis of systematic analysis (including user demand analysis, data analysis and feasibility analysis), the overall design and detailed design of highway geological hazard risk assessment information system in Yi Town are carried out. The system adopts C / S model.Based on ArcSDE Geodatabase and SQL Server technology, the spatial database of geological hazards along the Yi-town highway is designed and established. Finally, ArcGIS Engine is selected as the secondary development technology, and the system is developed on the Visual Studio2010 development platform by using the object-oriented visual programming language C #.A risk assessment information system for highway geological hazards in Yi Town based on ArcGIS Engine is constructed, which integrates the functions of query and retrieval, statistical analysis, risk assessment, print output and data dynamic maintenance.The establishment of the system can provide technical support for geological disaster management departments and highway administration departments along the Yi-town highway in disaster prevention and mitigation as well as ensuring road safety. It is of great application value.
