論文摘要:

為了深入研究在豎井爆破擴(kuò)挖施工中不同延時(shí)時(shí)間對(duì)爆破效果的影響,總結(jié)分析現(xiàn)有相關(guān)研究后,綜合考慮研究需要,相對(duì) 全面地將延時(shí)時(shí)間設(shè)定為0、2、5、10、20、25、35ms,通過控制變量法只考慮不同延時(shí)時(shí)間對(duì)于研究主體的影響規(guī)律。利用動(dòng)力有限元 分析軟件LS-DYNA 建立通風(fēng)豎井延時(shí)爆破擴(kuò)挖數(shù)值模擬模型,計(jì)算得出不同延時(shí)時(shí)間以及不同間隔距離對(duì)應(yīng)的振速時(shí)程曲線、峰值 振速以及結(jié)構(gòu)失效情況,通過對(duì)計(jì)算結(jié)果的綜合分析,從多個(gè)角度確定了針對(duì)所模擬的工況最佳的延時(shí)時(shí)間為25ms,且得出了延時(shí) 爆破不同延時(shí)時(shí)間對(duì)減振效果的一些實(shí)用性規(guī)律,對(duì)于類似工程延時(shí)爆破技術(shù)設(shè)計(jì)及參數(shù)優(yōu)化具有一定的借鑒意義。
