Abstract

To study the effects of cyclic blast loading on shared rock in a neighborhood tunnel,taking Liuyuetian bifurcation tunnel as the engineering background,a 3D model of the bifurcation tunnel was constructed using the finite element software LS-DYNA.Based on the HJC constitutive model,the damage variable was introduced to simulate the cumulative damage evolution process of the remained rock in the neighborhood tunnel under cyclic blast loading,and explore the relation among shared rock’s damage degree,damage range and explosion number.According to the decay law of mass point vibration velocity in the damage zone,the relation among single blasting charge,the maximum damage range and the critical damage mass point peak vibration velocity was established through data fitting.Finally,the simulation results were compared with those of acoustic wave tests on site to verify the rationality and correctness of the numerical simulation results.The results showed that the numerical simulation results agree well with those of tests on site,and the maximum damage zone appears on arch shoulder of shared rock; compared with a single blasting,the cumulative damage range caused by cyclic blasting excavations increases obviously,while the critical damage mass point peak vibration velocity drops significantly.
