【正文】 ubway pylon type metro station, hope that through reasonable design of blasting scheme, reduce over break and under break, controlled blasting on the surrounding rock disturbance, in order to achieve security plete station construction, ensure the quality of construction. In this project is mainly to solve the problem of Qingdao Dunhua Road subway station the main line of the tunnel and admit blasting design, the first tower type metro station design method, chamber is more, construction is plex, on the surrounding rock pillar protection, tunnel cross section form, tunnel lining structure, construction method, initial supporting structure model, parameter and so on are new and higher requirements. Therefore in the blasting design process, we used a bench excavation, large diameter hollow hole, excavation, piecewise detonating method, at the same time, a detonation 山東科技大學(xué)學(xué)士學(xué)位論文 subsection delay blasting excavation patent technology, at the same time, a detonation subsection delay blasting excavation patent technology, the spirit of multiple drilling, charging less, short footage principle, strictly control the footage, single hole charge, in the design of the A cross passage, was also given to A cross passage and barrierfree elevators and one line the relationship between the inclined ladder, cutting holes and auxiliary eye position was adjusted, these technologies can effectively resolve the problems above, in practical engineering applications have achieved very good results. Keywords ： metro ， tower type station， drilling and blasting ， vibration control. 山東科技大學(xué)學(xué)士學(xué)位論文 目錄 1 緒論 ...................................... 1 課題的提出 .................................................................................... 1 國內(nèi)外研究情況及發(fā)展 ................................................................ 2 本課題研究的目的和意義 ............................................................ 6 研究方法 ........................................................................................ 6 2 工程概況 ................................... 7 工程地理位置 ................................................................................ 7 工程地質(zhì) ........................................................................................ 7 地質(zhì)構(gòu)造及地震烈度 .................................................................. 12 周圍環(huán)境 ...................................................................................... 13 3 開挖方案 .................................. 15 地鐵隧道施工的主要技術(shù) .......................................................... 15 隧道暗挖施工方法 ...................................................................... 17 開挖方案選擇 .............................................................................. 25 本章小結(jié) ...................................................................................... 25 4 鉆爆設(shè)計 .................................. 26 主線隧道鉆爆設(shè)計 ...................................................................... 26 A 通道鉆爆設(shè)計 ........................................................................... 41 B、 C 通道鉆爆設(shè)計 .................................................................... 47 山東科技大學(xué)學(xué)士學(xué)位論文 本章小結(jié) ...................................................................................... 53 5 爆破振動驗算 .............................. 54 爆破振動衰減規(guī)律 ...................................................................... 54 爆破振動安全允許標(biāo)準(zhǔn) .............................................................. 55 最大單段起爆藥量的計算 .......................................................... 56 爆破振動安全驗算 ...................................................................... 58 針 對爆破振動對居民影響應(yīng)采取的措施 .................................. 59 本章小結(jié) ...................................................................................... 60 6 起爆網(wǎng)路 .................................. 61 技術(shù)內(nèi)容 ...................................................................................... 61 附圖說明 ...................................................................................... 63 具體實施方式 .............................................................................. 63 本章小結(jié) ...................................................................................... 66 7 作業(yè)安全與質(zhì)量控制 ......................... 67 空氣沖擊波、爆破有害氣體與爆破飛石 .................................. 67 早 爆 ............................................................................................. 68 盲炮處理 ...................................................................................... 68 敷設(shè)導(dǎo)爆管爆破網(wǎng)路時應(yīng)注意的問題 ...................................... 69 敷設(shè)導(dǎo)爆索爆破網(wǎng)路時應(yīng)注意的問題 ...................................... 70 使用電力起爆系統(tǒng)應(yīng)注意的問題 .............................................. 70 鉆爆質(zhì)量的控制 .......................................................................... 71 山東科技大學(xué)學(xué)士學(xué)位論文 隧道貫通作業(yè) .............................................................................. 72 本章小結(jié) ...................................................................................... 73 8 設(shè)備配置與爆破器材準(zhǔn)備 ..................... 74 本章小結(jié) ............................................................................................ 76 9 經(jīng)濟技術(shù)指標(biāo) .............................. 77 本章小結(jié) ............................................................................................ 78 10 總結(jié)與展望 ............................... 79 參考文獻 .................................... 81 致謝 ....................................... 83 附錄 英文文獻翻譯 ............................ 84 山東科技大學(xué)學(xué)士學(xué)位論文 1 1 緒論 課題的提出 隨著城市現(xiàn)代化建設(shè)的飛速發(fā)展和城市化進程的加快，大城市的地面交通變得越來越擁擠，而人們對出行的要求又越來越高，解決乘車難最有效的途徑就是大量修建快速、便捷的軌道交通。 山東科技大學(xué)學(xué)士學(xué)位論文 Abstract The subway as a new means of city transportation has the advantages of high efficiency, energy saving, environmental protection, large volume, speeds, and has gradually been people39。 因此在爆破設(shè)計過程中，我們采用了臺階法開挖、大直徑中空孔、分部開挖、逐段起爆等方
