中文拼音 [bàolièzhǐshǔ]
爆裂指數
英文
decrepitation index-
Based on the theory of detonation dynamics and fracture mechanics and combined with engineering experiences, the parameters of soft rock tunnel hole charge and smooth blasting are analysized to enhance tunnel excavation proficiency in soft rock and smooth blasting. value scope of smooth blasting is acquired, which can give some experience for parameters design and construction of smooth blasting in soft rock tunnel excavation
摘要為提高軟巖巷道掘進效率和光爆效果,利用爆轟動力學和斷裂力學理論,分析了軟巖巷道掏槽及光爆參數,結合工程實踐經驗,得出了軟巖巷道光面爆破參數的取值范圍,對軟巖巷道爆破參數的設計和施工具有一定的指導意義。With artificial neural network to consider affecting the rock to crack in pre - split blasting, people have established the calculation of intelligence model system which can predict and forecast the result and overcome the lack of the theory, model and empirical formula. the system has very great realistic meaning in designing and guiding actual engineering. with the rock ' s crack in pre - split blasting as the studied object, the reason of crack of mineral and rock in pre - split blasting and the parameter design are studied in the paper
運用人工神經網路綜合考慮影響巖石預裂爆破成縫的因素,建立運算模型智能系統,可克服目前預裂爆破成縫理論、成縫模型、經驗公式的不足,對實際工程的設計與指導,具有很大的現實意義本文以巖石預裂爆破成縫作為研究對象,對礦巖的預裂成縫機理及其參數設計進行了研究。3 ) on the other hand, the gaussian heterogeneous anisotropic random fractured model might be a suitable model for the single - scaled and smooth heterogeneous media. the propagation of elastic waves, excited by an explosive point source in exponential ellipsoidal and gaussian heterogeneous anisotropic random fractured rocks, were simulated
模擬了爆炸點源產生的彈性波在指數橢圓型、 gaussian型非均勻各向異性隨機裂縫國防科學技術人學研究生院學位論文巖石中的傳播,討論了具有不同自相關長度的或者不同類型的非均勻各向異性隨機裂縫巖石對彈性波的散射。At first, the author has analyzed the theory, mechanism and shock - absorption in pre - split blasting, studied the rising of crack, expanding and stopping, and did various factors which influence on the crack of rock in pre - split blasting. the main factors have been determined to be the strength of mineral and rock, the diameter of drill, the type of explosive and the growth degree of crack. then, the author has researched bp neural networks " work principle, structure and defectiveness
