【正文】 V級圍巖下的支護(hù)結(jié)構(gòu)、各種圍巖條件下的施工方法、監(jiān)測、洞門等進(jìn)行設(shè)計。本隧道采用全封閉防水型襯砌結(jié)構(gòu)，利用 ANSYS 軟件，根據(jù)隧道埋深與地質(zhì)的情況，得出隧道在 山嶺 段二次襯砌中的受力與變形進(jìn)行驗算，并得出驗算結(jié)果。 高速鐵路與一般鐵路的最大區(qū)別是要考慮到空氣動力學(xué)效應(yīng)，因此在襯砌 的擬定上，不僅考慮了機(jī)車車輛類型、行車條件、線路條件等，同時也結(jié)合了高速列車隧道空氣動力學(xué)的影響。 關(guān)鍵詞： 高速鐵路隧道；結(jié)構(gòu)驗算； 有限元分析。 大學(xué)本科 畢業(yè)設(shè)計 (論文 ) 第 V 頁 Part Of The Tunnel Design Of In BeijngShanghai HighSpeed Rail Passenger Line In Zhangxia, ABSTRACT BeijngShanghai HighSpeed Rail Passenger Line is the largest and the highest technological content of a project, but also China39。s first worldclass highspeed railway. The whole line of it is about 1318 kilometers, with the existing BeijingShanghai railway parallel to the general, across the board for the new twolane, the design speed 350kilometers, the initial period operation speed 300 kilometers, altogether establishes 24 passenger stations. After the pletion of the BeijingShanghai highspeed railway, with already has the Beijing to Shanghai railroad realization passengers and cargo to diverge. By then, the BeijingShanghai highspeed train running the whole time just five hours, than at present between the BeijingShanghai express train about nine hours shorter, in a oneway passenger transport up to 8,000 million, a significant release of both the capacity of the BeijingShanghai Railway, so that the existing BeijingShanghai line of oneway cargo capacity was 130 million tons more than the ability to bee a major freight routes, the BeijingShanghai route to meet passenger and freight transport demand, a fundamental solution to the BeijingShanghaichannel transport capacity of the state of tension, real people by their deeds, smooth flow of goods. This in the domestic construction milestone, technical standards, the highest standards of green greenwide passenger—BeijngShanghai HighSpeed Rail Passenger Line . The import mileage of Zhangxia tunnel is DK427+980, export mileage isDK428 +672, and the total length of this tunnel is 672 meters. This tunnel pass through lowrelief terrain. This project characteistics has the plex environment. According to the special geological conditions and engineering large section of 大學(xué)本科 畢業(yè)設(shè)計 (論文 ) 第 VI 頁 the Liuyang River Tunnel features, many things had been designed, such as the rocksupporting structure under the IV V of the tunnel, the construction methods in all kinds of rock under the conditions, monitoring and so on. The tunnel was closed by the whole structure of waterresistant lining. According to the depth and geological condition of the tunnel, the forces and deformations of the 2nd lining for the obtained tunnel had been calculated, by the using of ANSYS software. Highspeed railway with the greatest difference between conventional rail is to take into account the aerodynamic effects, and therefore the formulation of the lining, not only takes into account the type of rolling stock, road conditions, route conditions, as well as a bination of highspeed train tunnel aerodynamic effects of . Key words: highspeed railway tunnel。 structure checking calculation。 numerical analyses with the finite element method。 大學(xué)本科 畢業(yè)設(shè)計 (論文 ) 第 1 頁 目錄 第１章 緒論及隧道概況 ................................................................................................... 1 工程概況 ............................................................................................................. 1 隧道工程位置 ............................................................................................. 1 隧道建設(shè)規(guī)模 ............................................................................................. 1 工程地質(zhì)和水文地質(zhì)特征 ..................................................................................... 2 地層巖性 .................................................................................................... 2 .................................................................................................... 3 ............................................................................................. 3 ........................................................................................................... 3 。 .......................................................................... 3 ............................................................................................. 3 隧道 圍巖分級 ...................................................................................................... 4 各段巖土工程條件評價及工程措施建議 ................................................................ 5 隧道進(jìn)口明挖段評價 .................................................................................. 5 隧道洞身段 ................................................................................................ 5 第２章 張夏隧道總體設(shè)計 ............................................................................................... 7 設(shè)計依據(jù)及范圍 ................................................................................................... 7 設(shè)計采用的標(biāo)準(zhǔn)、規(guī)范及規(guī)程 .................................................................... 7 設(shè)計范圍 .................................................................................................... 7 總體線位 ............................................................................................................. 7 隧道縱坡 ............................................................................................................. 7 隧道建設(shè)規(guī)模 ...................................................................................................... 7 軌道類型 ............................................................................................................. 7 主要技術(shù)標(biāo)準(zhǔn)與設(shè)計原則 ..................................................................................... 8 主要技術(shù)標(biāo)準(zhǔn) .......................
