近距离爆破对隧道衬砌影响的数值模拟研究
|
摘要
采用ANSYS/LS-DYNA对近距离爆破对隧道的影响进行了数值模拟,并将数值计算速度峰值结果与现场监测结果回归公式计算结果进行比较分析。结果表明:数值计算得到的速度峰值结果和回归公式计算结果吻合较好,采石场的爆破施工对隧道衬砌的安全不会产生不利的影响,数值模拟在研究爆破震动对衬砌的影响是可行的。
Using ANSYS/LS-DYNA to simulate the impact of the tunnel lining under the close blasting.The results of velocity of numerical calculation with the field monitoring results were compared with regression analysis formula.The results show that the velocity of numerical calculation results and the regression formula to calculate,the peak results agree well,quarry blasting for the tunnel lining is safe,using numerical simulation to study the tunnel lining under the impact of blasting vibration is feasible.
