摘要
采用LS-DYNA有限元模拟方法建立了水压爆破模拟模型,并对水压爆破进行了数值模拟。提出了水压爆破壁体受首次冲击波、底板反射压缩波、对面壁体反射压缩波和气泡脉冲等四种荷载作用的观点,为水压爆破准静压作用的原理提供了依据。
With LS-DYNA finite dement simulation method,the simulation model of hydrarlic blasting has been set up, and the numerical simulation to hydraulic blasting is carried out in this thesis. It has put forward that the wall of the structure will be affected by such four load functions as the first shock cave ,the compress cave of foundation reflection, the compress wave of the opposite wall and the bubble pulse, and offered a basis for the principle of approximate static presure function of hydraulic basting.
