【摘要】：山區(qū)公路作為特殊的帶狀工程，其經(jīng)歷路線長(zhǎng)，各路段面臨地形地貌、氣象水文等條件復(fù)雜多樣，導(dǎo)致山區(qū)公路洪災(zāi)發(fā)生頻繁，多處山區(qū)公路基礎(chǔ)設(shè)施被毀，對(duì)交通運(yùn)輸造成極大經(jīng)濟(jì)損失，因此山區(qū)公路洪災(zāi)防治問(wèn)題很突出。論文依托重慶市自然科學(xué)基金項(xiàng)目《山區(qū)公路山洪災(zāi)害綜合風(fēng)險(xiǎn)精細(xì)評(píng)估研究》，把巴南區(qū)11個(gè)鄉(xiāng)鎮(zhèn)作為研究區(qū)，對(duì)其進(jìn)行公路洪災(zāi)孕災(zāi)環(huán)境分區(qū)及危險(xiǎn)性評(píng)價(jià)；在此基礎(chǔ)上，對(duì)研究區(qū)域示范公路國(guó)道G65、省道S415進(jìn)行公路洪災(zāi)分析，得到研究區(qū)示范公路路段洪災(zāi)孕災(zāi)環(huán)境分區(qū)圖及危險(xiǎn)性評(píng)價(jià)結(jié)果。 利用災(zāi)變理論，對(duì)公路洪災(zāi)孕災(zāi)環(huán)境及危險(xiǎn)性評(píng)價(jià)指標(biāo)進(jìn)行取舍選擇，運(yùn)用專家意見(jiàn)構(gòu)造判斷矩陣，采用層次分析法確定各指標(biāo)權(quán)重值。利用ArcGIS的空間分析功能對(duì)研究區(qū)公路洪災(zāi)各指標(biāo)基礎(chǔ)數(shù)據(jù)進(jìn)行數(shù)字化提取，得到孕災(zāi)環(huán)境及洪災(zāi)危險(xiǎn)性指標(biāo)信息，利用GIS制圖功能繪制不同指標(biāo)單要素圖層。以孕災(zāi)環(huán)境及危險(xiǎn)性指標(biāo)數(shù)據(jù)庫(kù)為基礎(chǔ)，采用多因素綜合指數(shù)分區(qū)模型，，基于鄉(xiāng)鎮(zhèn)行政區(qū)，對(duì)研究區(qū)進(jìn)行公路洪災(zāi)孕災(zāi)環(huán)境分區(qū)及危險(xiǎn)性分區(qū)，此外對(duì)研究區(qū)示范公路路段進(jìn)行孕災(zāi)環(huán)境分區(qū)及危險(xiǎn)性分區(qū)。 論文研究區(qū)為重慶市巴南區(qū)的11個(gè)鄉(xiāng)鎮(zhèn)，基于公路洪災(zāi)鄉(xiāng)鎮(zhèn)區(qū)域孕災(zāi)環(huán)境及危險(xiǎn)性區(qū)劃理論及分區(qū)模型，得出各指標(biāo)指數(shù)范圍值，依據(jù)該值的臨界域進(jìn)行孕災(zāi)環(huán)境及危險(xiǎn)性分區(qū)。其中孕災(zāi)環(huán)境分區(qū)結(jié)果：危險(xiǎn)區(qū)面積238.73km2，占區(qū)域面積21.16%；高易發(fā)區(qū)面積248.66km2，占區(qū)域面積22.04%；中易發(fā)區(qū)及低易發(fā)區(qū)占區(qū)域面積56.8%。危險(xiǎn)性評(píng)價(jià)分區(qū)結(jié)果：高危險(xiǎn)區(qū)面積435.16km2，占區(qū)域面積38.57%；中危險(xiǎn)區(qū)面積360.57km2，占區(qū)域面積31.96%；低危險(xiǎn)區(qū)及微危險(xiǎn)區(qū)占區(qū)域面積29.46%。在此基礎(chǔ)上，論文以國(guó)道G65、省道S415作為示范公路，得到公路各路段孕災(zāi)環(huán)境及危險(xiǎn)性綜合指數(shù)，據(jù)此對(duì)其分區(qū)。其中公路洪災(zāi)孕災(zāi)環(huán)境分區(qū)結(jié)果：危險(xiǎn)區(qū)里程16.58km，占示范公路總里程20.31%；高易發(fā)區(qū)里程9.46km，占示范公路總里程11.59%；中易發(fā)區(qū)及低易發(fā)區(qū)占示范公路總里程68.10%。公路洪災(zāi)危險(xiǎn)性評(píng)價(jià)分區(qū)結(jié)果：高危險(xiǎn)區(qū)里程10.27km，占示范公路總里程12.58%；中危險(xiǎn)區(qū)里程45.41km，占示范公路總里程55.64%；低危險(xiǎn)區(qū)及微危險(xiǎn)區(qū)占示范公路總里程31.78%。
[Abstract]:As a special zonal project, mountain highway has a long route, various terrain and landforms, meteorological and hydrological conditions, which lead to frequent flood disasters and the destruction of many mountain highway infrastructure. Traffic and transportation caused great economic losses, so the mountain highway flood prevention problem is very prominent. On the basis of Chongqing Natural Science Foundation project "study on the comprehensive risk assessment of mountain highway mountain torrents", this paper takes 11 villages and towns in Banan as research areas to carry out environmental zoning and risk assessment of highway flood disaster prevention, on the basis of which, Based on the analysis of flood disaster of the national highway G65 and the provincial highway S415 in the study area, the zoning map of flood disaster prevention environment and the risk assessment results of the model highway section in the study area were obtained. The disaster theory is used to select the evaluation index of disaster environment and risk of highway flood disaster, the judgment matrix is constructed by expert opinion, and the weight value of each index is determined by analytic hierarchy process (AHP). By using the spatial analysis function of ArcGIS, the basic data of highway flood index in the study area are extracted digitally, and the disaster environment and flood risk index information are obtained. The mapping function of GIS is used to draw the single element map layer of different indexes. Based on the database of disaster environment and risk index, the multi-factor comprehensive index partition model is used to divide the environment and risk of highway flood disaster in the study area based on the township administrative region. In addition, the study area demonstration road sections of the disaster environment and hazard zoning. The research area of this paper is 11 villages and towns in Banan district of Chongqing. Based on the theory of disaster environment and risk regionalization and zoning model, the index range of each index is obtained. According to the critical region of this value, the disaster environment and risk zoning are carried out. The results showed that the area of risk area was 238.73km2, the area of high risk area was 21.16km2, the area of high risk area was 248.66km2, the area was 22.040.The area of middle and low risk area was 56.8. The results of risk assessment were as follows: the area of high risk area was 435.16km2, the area of area was 38.57, the area of middle risk area was 360.57km2, and the area of low risk area was 31.96km2, and the area of low risk area and micro-risk area was 29.46. On this basis, the paper takes G65 and S415 as demonstration roads, obtains the comprehensive index of disaster environment and risk of each section of highway, and divides them according to them. The results showed that the mileage of dangerous area was 16.58km, the mileage of demonstration highway was 20.31, the mileage of high susceptible area was 9.46km, the mileage of demonstration highway was 11.59km, the mileage of model highway was 68.10km in middle susceptible area and low prone area. The results of highway flood risk assessment are as follows: the mileage of high risk area is 10.27km, the total mileage of demonstration highway is 12.58, the mileage of middle dangerous area is 45.41km, the total mileage of demonstration highway is 55.64km, and the mileage of low risk area and microhazard area is 31.78.
