摘要(Abstract)：

以福平铁路隧道爆破开挖工程为例,针对福平铁路施工中新建隧道上跨既有隧道的特殊工况,采用ANSYS有限元软件对爆破方案进行模拟计算,求得最大主应力所在的位置和振动波形。将实际监测结果与模拟结果的振动波形进行对比,并分析振动峰值和频率特征。结果表明,二者的振动峰值近似相等但频率特征有所不同,说明ANSYS数值模拟能找到最危险位置并预测最大振速,可以指导工程实际。
Taking the excavation project of Fuping railway tunnel as an example,ANSYS finite element software was used to simulate the blasting scheme for the new tunnel in Fuding railway construction and the position of the maximum principal stress and vibration waveforms were obtained.The actual monitoring results were compared with the vibration waveforms of the simulation results.The vibration peak and frequency characteristics were analyzed.The results show that the vibration peaks are similar to each other but the frequency characteristics are different.It shows that ANSYS numerical simulation can find the most dangerous position and predict the maximum vibration velocity,which can guide the engineering practice.
