| 摘 要： | 本文视土岩介质为横观各向同性均匀弹性体,用正弦波的半周期模拟爆炸冲击荷载的情况,利用三维弹性动力学的基本原理研究了爆炸冲击荷载作用下半无限弹性介质的动力响应,并给出了算例的解析解结果。该方法可用于解决土木工程基础开挖中预留保护层及建筑物爆破振动防护的问题。

| Abstract: | Considering soil and rock media as a transversely isotropic elastic body and the condition of a blasting impact load simulated by a half period of sine wave, the three dimensional theory of elastic dynamics is used to solve the dynamical response of elastic media in half space with a blasting impact load subjected to its surface, the analytic solutions of an example is presented in this paper. This method can be used to solve some problems such as how to obligate to protect structure from blasting vibration in exacvation of rock foundation. |
