After a review of the development of gis, the general situation of sichuan province " s traffic lines, along with the gis application and prospect on geologic hazards and traffic managements is introduced in this thesis . based on the discussion above, the significance and research of prevention and control hazard information system for traffic lines of sichuan province are put forward 本文回顧了地理信息系統(tǒng)(gis)的發(fā)展史,介紹了四川省的交通線路現(xiàn)狀,在分別論述了gis在地質(zhì)災(zāi)害信息處理及交通管理方面的應(yīng)用現(xiàn)狀及發(fā)展趨勢(shì)的基礎(chǔ)上,確定了四川省交通線路防災(zāi)減災(zāi)系統(tǒng)的開(kāi)發(fā)意義和本文的研究?jī)?nèi)容。
Whereafter, based on the analysis on the flood influence for traffic lines, the research is centered on the following parts : firstly, the destroying modes, reasons and mechanism of flooded lines are discussed, and the frameworks and countermeasures of preventing and controlling hazards system are put forward; secondly, the ways of region forecasting for the landslide are analyzed and the automation of landslide forecast for certain site through visual programming is realized . furthermore, the function of dynamic segmentation in arc view is made use of to realize the forecast result's visualization; thirdly, the reasons and patterns of roadbed subsidence are discussed and the methods of forecasting subsidence based on the gm ( 1, 1 ) model are put forward . then the applications of the arcview software and its extended module on the study of roadbed subsidence are debates upon; fourthly, an analysis on the sources of flood for traffic lines, which situate in the reservoir coverage area, is given 接著,論文探討了山區(qū)交通線路災(zāi)害的特點(diǎn)、分類、時(shí)間和空間分布規(guī)律以及災(zāi)害的防治原則和對(duì)策等;然后,以洪水災(zāi)害對(duì)交通線路的毀壞為主線,重點(diǎn)研究和分析了以下幾個(gè)問(wèn)題:第一,探討了洪水對(duì)交通線路的破壞方式,水毀原因以及水毀機(jī)理,并提出了交通線路水毀防御系統(tǒng)框架和對(duì)策;第二,分析了雨季邊坡塌方災(zāi)害的區(qū)段預(yù)測(cè)方法;通過(guò)可視化編程,編制了雨季邊坡塌方災(zāi)害的工點(diǎn)預(yù)報(bào)程序,并結(jié)合arcview實(shí)現(xiàn)了預(yù)測(cè)結(jié)果的可視化;第三,對(duì)路基沉陷原因和模式進(jìn)行了分析,并提出利用gm(1,1)模型對(duì)路基沉陷區(qū)進(jìn)行分析和預(yù)測(cè),最后論述了arcview軟件及其擴(kuò)展模塊在沉陷區(qū)研究分析中的應(yīng)用;第四,對(duì)汛期庫(kù)區(qū)線路災(zāi)害的原因進(jìn)行了分析,并探討了利用數(shù)量化理論對(duì)路基防護(hù)工程抗洪能力進(jìn)行預(yù)測(cè)的意義;第五,提出從風(fēng)險(xiǎn)的角度對(duì)交通線路的防災(zāi)減災(zāi)進(jìn)行管理,對(duì)風(fēng)險(xiǎn)估計(jì)的相關(guān)問(wèn)題進(jìn)行了論述,并探討了交通線路水害危險(xiǎn)區(qū)段的劃分問(wèn)題。
