【摘要】：隨著我國公路隧道建設(shè)事業(yè)的發(fā)展，積極響應(yīng)國家節(jié)能減排的號召，公路隧道通風(fēng)領(lǐng)域勢必會(huì)出現(xiàn)新的運(yùn)行理念和結(jié)構(gòu)形式，雙洞互補(bǔ)式通風(fēng)便是其中之一。該通風(fēng)方式充分利用了隧道上下行存在的較大通風(fēng)差異，采用了“雙洞互補(bǔ)”的原理，巧妙地解決了隧道通風(fēng)需要修建豎井的問題，有著良好的社會(huì)和經(jīng)濟(jì)效益。 雙洞互補(bǔ)式通風(fēng)理論研究尚處于初期階段，雖在工程實(shí)際中得以應(yīng)用，但對其適用性以及具體運(yùn)行模式還有待于進(jìn)一步探討。本文則基于雙洞互補(bǔ)式通風(fēng)的基本原理，重點(diǎn)圍繞其適用性展開研究，并結(jié)合具體工程實(shí)際應(yīng)用，通過需風(fēng)量計(jì)算分析，給出了互補(bǔ)式通風(fēng)的適用條件，包括隧址環(huán)境、隧道長度、隧道縱坡以及交通量等影響條件；此外，本文還建立了互補(bǔ)式通風(fēng)換氣系統(tǒng)的三維立體模型，并利用計(jì)算流體力學(xué)軟件Fluent對其運(yùn)行效果進(jìn)行了數(shù)值模擬，更深入地驗(yàn)證了互補(bǔ)式通風(fēng)的適用性；緊接著，，本文還以應(yīng)用雙洞互補(bǔ)式通風(fēng)系統(tǒng)的大別山隧道為工程依托，對其進(jìn)行了交通量、風(fēng)速及污染物濃度等現(xiàn)場實(shí)測，分析了不同工況下隧道通風(fēng)運(yùn)行情況，并將實(shí)測結(jié)果與數(shù)值模擬結(jié)果進(jìn)行了對比分析。 本文通過以上分析總結(jié)，在雙洞互補(bǔ)式通風(fēng)適用性及運(yùn)營方面得到了一系列有益的結(jié)論，對雙洞互補(bǔ)式通風(fēng)的推廣應(yīng)用有一定的現(xiàn)實(shí)意義，并為大別山隧道等實(shí)際應(yīng)用工程的運(yùn)營管理提供了一定的參考價(jià)值。
[Abstract]:With the development of highway tunnel construction in China, and in response to the call of national energy saving and emission reduction, new operational concepts and structural forms will inevitably emerge in the field of highway tunnel ventilation, one of which is the complementary ventilation with two holes.This ventilation mode makes full use of the large ventilation difference between the upper and lower tunnels, adopts the principle of "two holes complementing", and skillfully solves the problem that the shaft needs to be built in the tunnel ventilation. It has good social and economic benefits.Although the theory of complementary ventilation of double holes is still in the initial stage, it is applied in engineering practice, but its applicability and operation mode still need to be further discussed.Based on the basic principle of two-hole complementary ventilation, this paper focuses on its applicability. Combined with the practical application of specific projects, the suitable conditions of complementary ventilation, including tunnel environment, are given through the calculation and analysis of air demand.In addition, the three-dimensional model of complementary ventilation and air exchange system is established, and the numerical simulation of its operation effect is carried out by using the computational fluid dynamics software Fluent.The applicability of complementary ventilation is verified more deeply. Then, based on the Dabie Mountain Tunnel with a two-hole complementary ventilation system, the field measurements of traffic volume, wind speed and pollutant concentration are carried out.The tunnel ventilation operation under different working conditions is analyzed, and the measured results are compared with the numerical simulation results.Through the above analysis and summary, a series of beneficial conclusions have been obtained in the applicability and operation of dual hole complementary ventilation, which has certain practical significance for the popularization and application of double hole complementary ventilation.It also provides a certain reference value for the operation and management of Dabie Mountain Tunnel and other practical application projects.
