摘要
本义用约束节理单元法模拟应力波在节理处的传递过程。推导了动态约束节理单元的有限单元方程和数值分析公式以及碰撞、放释条件，并针对奥地利某公路隧洞工程进行了爆炸应力波在节理岩体中传播的有限元分析。
The wave prowation in jointed rock is analysed by FEM with a special joint element de-veloped in this peper. The formulas of FEM for the constraint joint element is derived as well as the im-pactreleasing conditions. With the proposed numerical medel, an Anstrian highway tunnel under blastloading is analysed with consideration of the joint behaviors.
