摘要
运用DYNA - 2D对近距侧爆情况下隧道周边围岩的动态震动场进行了数值模拟研究 ,分析了隧道周边围岩质点震动的分布特征 ,并借助大量测试数据分析对数值模似分析结构进行了验证。另外还在对现场震动测试数据分析的基础上 ,论述了爆破条件、地质条件对震动衰减的影响。
The DYNA 2D was applied to analyze the regular distribution pattern of the blasting induced vibration field occurred at contour of adjacent tunnel. On the basis of the analysis of the numberical results of the field vibration testing, the relationship between blasting features, geological conditions and vibration attenuation is discussed.
