【摘要】：近年來,隨著國民經(jīng)濟的迅猛發(fā)展,交通隧道“長、大、深”的特點日趨顯現(xiàn)。特長公路隧道的規(guī)模和數(shù)量也在日益增多,而特長公路中通風(fēng)因素成為了隧道運營及管理的關(guān)鍵。本文以山西省交通廳科技項目“特長公路隧道輔助通道設(shè)置及施工關(guān)鍵技術(shù)研究”為依托,以云山隧道1#豎井,3#斜井、寶塔山隧道地下風(fēng)機房為研究對象,采用資料調(diào)研、理論分析、數(shù)值模擬相結(jié)合研究方法,對輔助通道合理設(shè)置、地下風(fēng)機房防災(zāi)救援情況進(jìn)行研究,主要的研究成果如下：1.通過對隧道發(fā)生火災(zāi)實例調(diào)研,系統(tǒng)分析了火災(zāi)的發(fā)生原因、特點及危害,并從理論上得出了計算火災(zāi)溫度及煙流濃度的計算方法。2.依托寶塔山地下風(fēng)機房結(jié)構(gòu),基于FDS和Building exodus數(shù)值模擬軟件,建立風(fēng)機房三維模型,分別對火災(zāi)情況及人員逃生進(jìn)行模擬,給出不同情況下隧道地下風(fēng)機房火災(zāi)及逃生參數(shù),提出可利用逃生時間大于必須逃生時間作為風(fēng)機房防災(zāi)設(shè)計依據(jù),為風(fēng)機房防災(zāi)類似設(shè)計提供參考。3.根據(jù)云山隧道斜井的結(jié)構(gòu)形式及設(shè)置方式,基于CFD(流體動力學(xué))理論,利用FLUENT數(shù)值模擬軟件,對不同角度斜井的運營通風(fēng)進(jìn)行模擬,再通過伯努利方程、能量方程對其能耗進(jìn)行計算。4.從快速施工出發(fā),提出特長公路隧道采用小角度斜井用來增加施工工作面,而運營階段開挖大角度斜井或豎井作為通風(fēng)道,施工采用的小角度斜井作為逃生救援通道的新型輔助通道設(shè)置方法,并對其可行性進(jìn)行分析。
[Abstract]:In recent years, with the rapid development of the national economy, the characteristics of traffic tunnels "long, large and deep" have become increasingly apparent. The size and number of extra-long highway tunnels are also increasing day by day. The ventilation factor in the super long highway has become the key to the tunnel operation and management. Based on the scientific and technological project of Shanxi Provincial Communications Department, "the study on the key Technology of setting up and Construction of the Auxiliary Tunnel of the extra long Highway Tunnel", this paper takes the shaft of the Yunshan Tunnel, which is located in the Shaft of the Yunshan Tunnel, as an inclined shaft. The underground fan room of Baotashan Tunnel is studied by the methods of data investigation, theoretical analysis and numerical simulation. The reasonable setting of auxiliary passage and disaster prevention and rescue of underground fan house are studied. The main research results are as follows: 1.Through investigating the fire cases in the tunnel, the causes, characteristics and harm of the fire are analyzed systematically. The calculation method of fire temperature and smoke concentration is obtained theoretically. 2. Based on the structure of underground fan room in Baota Mountain and based on FDS and Building exodus numerical simulation software, the three-dimensional model of fan room is established. The fire situation and personnel escape were simulated respectively, and the fire and escape parameters of tunnel underground fan room were given. It was put forward that the escape time could be more than the necessary escape time as the basis for the disaster prevention design of the fan house. According to the structure form and setting mode of inclined shaft in Yunshan tunnel, based on the theory of fluid dynamics, using FLUENT numerical simulation software, the operation ventilation of inclined shaft with different angles is simulated. The energy consumption is calculated by Bernoulli equation and energy equation. Starting from the rapid construction, it is put forward that the super-long highway tunnel uses small angle inclined shaft to increase the construction face, while the large-angle inclined shaft or shaft is excavated as the ventilation passage in the operation stage. The small angle inclined well is used as a new auxiliary channel setting method for escape and rescue channel, and its feasibility is analyzed.
