摘要
在岩石隧道的施工中,爆破施工是一种常用的方法。隧道围岩中存在的节理裂隙很大程度上影响着爆炸应力波的传播。文章利用LS-DYNA有限元分析软件,通过三维数值模模拟,分别从振速、能量和强度等方面研究节理对爆破应力波传播的影响。
In the construction of rock tunnels, blasting is a common method. The joint fissures in the surrounding rock of the tunnel affect the propagation of the explosive stress wave to a great extent. In this paper, LS-DYNA finite element analysis software is used to simulate the influence of joints on the propagation of blasting stress wave from the aspects of vibration velocity, energy and intensity.
