【摘要】 处于深部的岩体内部积累了很高的弹性应变能,动力扰动可以触发深部岩体发生动力失稳。先用RFPA程序模拟了岩石中应力波传播及岩石的变形与破裂过程,以验证程序在模拟动态载荷下岩石破裂过程的有效性。然后,模拟了处于静态地应力作用下的巷道在动态扰动作用下的破裂过程。数值模拟表明, 对于不同地应力状态的巷道,动态扰动对其产生的影响不同;故开展动态扰动触发巷道破坏的研究是非常有现实意义的。更多还原

【Abstract】 Since much percolation have been seeping on the Yatang reservoir dam toe after the main project of the reservoir was finished, used safety monitoring system, the monitoring was applied to monitor the seepage for the second impounding water test. Based on the monitoring data, the seepage position and harm degree were thoroughly analyzed and a preliminary forecast was given in the paper.更多还原
