| 摘 要： | 以某双线隧道为研究对象,运用ANSYS/LS-DYNA程序就爆破动荷载对隧道结构影响进行有限元分析,获得了掘进隧道和相邻隧道质点振速、单元最大主应力分布特征,计算得到质点峰值振速与实测结果相对误差不超过8%.数值模拟的最大主应力结果表明:掘进隧道右侧墙受爆破振动影响最大,拱肩次之,拱脚处爆破影响最小;相邻隧道迎爆侧受爆破振动影响严重,侧墙处影响最大,拱顶次之,背爆侧受爆破影响小. |

| Abstract: | Taking a double-track tunnel to study, the tunnel structure effects under blasting load were analyzed by the ANSYS/LSDYNA program, and the features of the vibration velocity and maximum principal stress were obtained, the relative error between the calculated peak particle velocity and the measured results is less than 8% by comparing the simulation results and measured data. Simulation results of the maximum principal stress showed that the right side wall of construction tunnel was the most urgently affec... |
