摘要
爆炸荷载对地下结构的影响是工程界关注的重要问题。基于AUTODYN软件,采用SPH与FEM耦合的模拟方法,模拟和研究了近地面爆炸冲击荷载作用下,地下结构的动态响应过程。研究结果表明,爆炸荷载属于短时间冲击荷载,结构损伤破坏与加速度变化剧烈程度相关,在实际工程中应予以注意。
The effect of blast loading on the underground structure is an important issue in engineering. Based on the AUTODYN software,using coupling method of SPH and FEM,the dynamic response of underground structures under the near-surface blasting load has been simulated and studied. The results showed that blast loading belongs to short-term load,structural damage is related to the degree of the rapid change of acceleration. All of that should be noted in the actual project.
